European culture started with the era of migrations, on the ashes of the roman empire, but, contrary to popular belief, there is no continuity between the classical culture and the european culture as it stands today.
Every scientific discovery until now was a proof that this or that teaching of the christians is absolutely wrong and was considered heresy.
I am not the child of a j.ewish god. I know who my parents are. LOL
