Does Christianity originate from sun worshipping religions?

Please check out this video and see if you are interested in knowing more about Acharya S' work.  I have purchased this Christ in Egypt book and have only touched upon a mere speckle of pages.  I am interested in knowledge about Christianity and have not denounced the religion of Christianity entirely.  I have opened my mind up to the possibility that indeed Egyptian religion closely mimics our current understanding of the Christian religion.  Because of this, I have wanted to study the works of this author D.M. Murdock aka Acharya S.   She seems to know her stuff and I just wanted to give a taste of what she thinks with this video I found on YouTube.  Please let me know what you think as you review this and other videos that she has put out there on the subject matter.
