Interesting, here is a photo of what is claimed to be Horus's crucifixion:
It does seem to be some uncanny relations between these different Gods and I do consider Jesus to be a God or the God, though I understand it is a little more complex than that summation. But for the sake of clarity of the question I am just addressing Jesus as a God.
I have heard references to astrology in driving some of these coincidental factors such as the Star in the East, December 25th and even maybe Sunday as the day of praise for some Gods of history. But what about the 12 disciples, virgin birth, miracles, crucifixion, 3 day death and resurrection. These aspects of multiple Gods' stories from different societies transcend particular star patterns and celestial movements.
Is there perhaps a historical influence from older societies on the stories in the Bible or perhaps maybe there are some natural human psychological tendencies for purity (virgin birth) and guilt (crucifixion) and ego (desire for a survivor who was born from purity and made to suffer that is one of us, is human) that drives humans to tell these spiritual tales to comfort the very minds that create them.
