Kindly elaborate as to HOW YOU KNOW Jesus never existed.
Lots of guys named Jesus have existed. I went to school with one. I helped one with his computer a month or two ago. Since the name, or its Aramaic variant, go back to Roman times, it is completely unremarkable to imagine there were any number of Jesuses alive then as well.
So it is entirely possible that there was a Jesus or two or three who were used as the basis of the biblical tales. Probably at least two given the big gap in the middle.
So the next thing is could the stories be true? The answer is of course no. We now have a pretty good understanding of how things work and the stories in the bible are obviously myths and not actually possible. This is backed up by the numerous errors and inconsistencies and by how the tale grows more fanciful as it is told.
Its just a book of Jewish myths and propaganda much like the Iliad or the Upanishads. This is so obvious that it is an amazing testimony to early indoctrination that any one can stand to pretend they "believe." A living testimony to the error of group think.
