Okay, I've waited long enough to reply on this one. It's been a good 3+ days, and I've been researching, and slacking, to get this done. So, I think I've finally gotten my conclusion.
Now, your video starts off with saying that Egyptian mythology is based on astrology, which is for the most part correct.
His analysis on good and evil being equal but opposite forces doesn't work in Judeo-Christian aspects because the Judeo-Christian world (or at least those of us who have actually read a bible) know that the first evil being, and the one who influenced all the rest in some way shape or form (Satan, or Lucifer), was created by God. He has no power over him, and actually, when the time comes, he'll be sent to hell in which he will be burning. (Hell was originally intended for Satan and all those who follow him. Jesus makes it clear that those who are not with God [following him the way he wants you to], then you're very well against him. And if you're against him, you're going to the same place that's meant for Satan. Hell! YAAY! (In all seriousness though, it's a place you don't want to end up. Think about getting burnt by napalm while boiling in a giant pot of extremely hot pig fat. Now times that by 1,000,000. That's not even close to how bad hell is.
Now, Satan has, quite literally, no power over God. The book of Job makes this pretty clear, because Satan actually has to ASK God before he can do anything, despite the fact that he's already been kicked out of heaven. He still has to abide by what God says.
He then goes on later, to say that Jesus is a sun god. I don't think he understands the difference of the words sun and son. The sun is a creation by God, whereas Jesus is the son of God. (Ultimately a part of him. God is a whole confusing topic in itself, consisting of 3 parts and all).
Jesus is not a sun god. If he was, then people who believed in him would believe that the sun is God, and God says a big no no about this back early on in the Old Testament, during the Exodus, and a little bit into the nations of Israel with the major prophets. Here's just one quote:
"And when you look up to the sky and see the sun, the moon and the stars - and the heavenly array - do not be enticed into bowing down to them and worshipping the things the LORD your God has appointed to all the nations under heaven." (Deuteronomy 4:19)
This makes it pretty clear that God wants the people to stay away from Astrology. Astrology was created by a misunderstanding of the stars.
Furthermore, it would also break one of the commandments (of all the law that was abolished with Jesus, the 10 commandments stayed), and it was to not commit idolatry. Worshipping the sun is a form of "graven image", which is a form of idolatry.
As for the birthdays of the individuals:
Horus was born on December 25th. The date was spread across the western world of that time.
Christians adopted the date as the birth of Christ. (Early Chrsitians adopted a lot of things way back then, typically re-defining pagan symbols into Christian symbols.)
Nobody knows his birthday, but the time of the year that the herders saw Jesus was not in December. No, in december Judea would be raining all over, and the herders wouldn't be able to bring their flocks and such elsewhere.
Now, on to the virgin birth!
Mary was visited by an angel of the lord. He simply told her, "Behold, thou shalt conceive in thy womb, and bring forth a son and shalt call his name JESUS." (Gospel of Luke 1:31) Mary was a virgin, as all the biblical accounts of her say she was. But, nontheless, she conceived him. His parents were Mary, and Joseph. (Though technically, he wasn't the real son of Joseph.)
We're gonna kill two birds with one stone here. Horus's father was Osiris and Isis.
Now, the name Joseph means increaser, and Mary's name means bitter. Osiris's name means god of death, and Isis's name means the throne. Just to make sure that you don't get this confused, the names mean nothing alike, and ARE nothing alike. Let's move on now.
There's different versions of the story from the Egyptian book of the dead, but from what I read, Isis DID have sex with Osiris. Even worse, Isis was Osiris's sister... and she had sex with him while he was DEAD! Excerpt below:
"His sister [Isis] hath protected him..."
"She made light with her feathers, she created air with her wings, and she uttered the death wail for her brother, She raised up the inactive members of who's heart was still, she drew from his essence, she made an heir, she reared the child in the lonliness, and the place where he was not known, and he grew in strength and stature, and his hand was mighty in the house of Keb. The company of gods rejoiced, rejoiced at the coming Horus, the son of Osiris, who's heard was firm, the triumphant, the son of Isis, the heir of Osiris."
-Hymn to Osiris, Egyptian book of the dead
Next is the birthdays. The video claims that Jesus was born on December 25th. Jesus wasn't born on December 25th though. That was a pagan holiday originally, (probably the Horus one, after all it had influenced Greece and Rome). All we can say about Jesus's birth is that it cannot be in the winter. Winter in the land of Canaan (Israel) is typically... uh... very wet and rainy. This wet and rainy weather wouldn't have allowed for the shepards to bring their flocks and sheeps with them to go to Jesus's house in Bethleham. (Note that he doesn't stay in Bethleham for a while, but moves down to Egypt, and then later to a Jewish city named Nazareth - which actually during that time scale fulfilled a few prophecies about him right there. All of these were involuntary actions that he had no control over, where his parents would bring him.)
Speaking of Shepards though, Horus was never visited by angels or shepards.
There was also no star for Horus. Just an FYI, his birth wasn't really marked by anybody, or known by many really. No signs at all for his birth. Referenced here: "She reared the child in lonliness..." - nobody saw Horus being born - except for Isis - and nobody witnessed or knew him while he grew up. "... and the place where he was not known, and he grew in strength and stature."
Horus had more than 12 followers. Possibly 16 or 20. However, Jesus had more followers too. He had 12 original disciples, but there were more following him. At one point, Jesus had thousands of people following him, however for other reasons that to know that he was the son of God. They more likely followed him because they wanted stuff from him. "Jesus answered them and said, "Veryily, verily, I say unto you, ye seek me not because ye did eat of the loaves, and were filled." (Gospel of John 6:26, King James Translation)
Horus was never baptized. Jesus was.
Horus did not walk on water. The Egyptian book of the dead mentions none of this, as far as I can tell.
Horus and Jesus DID perform miracles, but of different scopes and such.
Horus didn't bring Osiris back to life. Jesus DID bring Lazarus back to life (and himself too.) [Lazarus means "God is helper", so there is still no correlation between Osiris and Lazarus at all].
Also, Horus was not crucified, or resurrected, he did not die for anybody's sins.
Jesus's coming was to do this: fulfill the law of Moses (which no human had ever done, or has done. Jesus is the only one who has completed it in full.), die for our sins (specifically so that people wouldn't have to transfer their sins to an animal by sacrificing it to God. God didn't like the idea in the first place, and would rather people not to sin. He actually speaks this to the people.) and then get resurrected so that his followers would truly believe. In the place of the Mosaic law, now in order to get to heaven, all you'd have to do is believe in God, and when you sinned, repent.
He also visited them some times after his resurrection, and when he finally rose into heaven, the people who followed him were convinced to spread the word. They spread the gospel to anybody and everybody, and Christianity spread like crazy, soon reaching Rome itself, and making it the official Roman religion. (However, Catholicism developed after that, which is well known for it's corruption of the scriptures. It also contradicts itself in more ways then one, and many Christians don't even look at Catholicism as a real branch of Christianity.) These apostles were willing to die to spread the message across, and of course, most of them did, save for one. John, who later wrote the book of Revelation, the well known last book of the bible. (One of the many books that had end time scriptures in it. The bible is actually 30% end time prophecy, but it gets overlooked in many churches today).
These apostles have their own book, the book of ACTS, and one of the apostles, Paul, wrote letters to many churches which we now know as the bulk of the new testament, consisting of the books of Romans, 1st and 2nd Corinthians, Galatians, Ephesians, Philippians, Colossians, 1st and 2nd Thessalonians, 1st and 2nd Timothy, Titus, Philemon and Hebrews. There are other apostle's letters too, including the general epistles of James, 1st and 2nd of Peter, 1st 2nd and 3rd of John, and Jude.
Here's some other things linking Horus to Osiris, and differing the Jesus - Osiris story.
"Thy son Horus is firmly placed on thy throne."
-Horus taking Osiris's throne.
"... and I am Horus who taketh possession of his throne for him."
-Jesus doesn't take the throne of God. He stands by his throne, and gives forgiveness to those who believed.
"9. Horus - the great god"
-texts relating to the weighing of the heart of Ani, Egyptian book of the dead
-Jesus is never mentioned (at least not in the gospels) as the great god. He is the son of God, a piece of God. The Father judges, the Son forgives. The father is most prelavent in the Old Testament, though he makes his appearances in the new testament too.
"Horus, the son of Isis" ('nuff said there).
-The SPEECH OF HORUS TO OSIRIS IN INTRODUCING ANI TO THEM
Lastly, here's some extra evidence for the existance of Jesus Christ.
Thallus wrote about Jesus. His works are so old that they don't really exist anymore, but somebody quoted him. I believe that Thallus wrote about Jesus's life, however his writings, like much of Plato's, are all gone.
Tacitus wrote about him. Tacitus is a really well known and trusted ancient historian, who speaks of Jesus in one of his books - in which he writes that Jesus lived, preach, and was crucified in Judea by Pontius Pilate, who was the executioner over Judea, Samaria, and Idumaea.
I don't wish to place any more names down, but plenty of more names are located in source 6 below.
Thank you for reading, if you have any counter evidence, then please state it. If not, then this is closed with an accurate statement that he is real.
