Is Snape Voldemort's son?

Hi, I'm new here.  My friends and I have a crazy theory.  Being that 
Snape's mother's Potions book was 50 years old (the book Harry was 
using in book 6), we decided she must have been at Hogwart's with 
Voldemort.  So, what if she had a brief affair with him, got pregnant, 
and that is why her husband hated her.  Also, if Dumbledore found out 
about it, and he was the one who told Snape, that could have been what 
brought Snape to his side.  That could be why Dumbledore trusted him so 
fully.
What do you all think?  Has anyone else heard this crazy theory of 
mine?  

I also do believe that Harry has a Horcrux in his scar but I 
desperately want him to live!
