How do Christians respond to and/or explain the similarities between other societies' Gods and that of Jesus God: Attis


Born of a virgin
Born on December 25th
Crucified
Dead for 3 days
Resurrected


God: Krishna


Born of a virgin
Star in the east
Performed miracles
Resurrected


God: Dionsyus


Born of a virgin
Born on December 25th
Performed miracles, including turning water into wine
Referred to as the "King of Kings"
Referred to as "Gods only begotten son"
Resurrected


God: Mithra


Born of a virgin
Born on December 25th
12 Disciples
Performed miracles
Dead for 3 days
Resurrected
Sunday is day of worship for Mithra


And the most striking and seemingly the base for all other mythologies:

God: Horus


Born on December 25th
Born of a virgin
Star in the east
Adored by 3 kings
Teach at 12
Baptized at 30
12 Disciples
Performed Miracles
Known as "Lamb of God", "The Light"
Crucified
Dead for 3 days
Resurrected


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.

I will post later using this information here, but for now, I have copied the image supplied by Jayarathina Madharasan

It seems that there are actually not as many similarities as certain people on the internet would like you to believe.
