Asking when Jesus will return is like asking when santa will return. Not in the sense that they are affiliated with the same December date, but because the use of the word "returning" implies that he was here at one point. And implying that he was on earth at one point also implies his existence. Did a man named Jesus exist 2000 years ago? possibly, but I can assure you that if he did, he was no son of God or miracle worker in any way. Just a normal walking human that came about through the same evolutionary process as all humans have. Only with him, false stories have been tied to his name to create a focal point for a deluded group of people (and most of these stories, everything from the virgin birth, to walking on water, to death and resurrection, are parallel to the stories of the Egyptian god Horus, and all records of Horus have been historically proven to pre-date christ, so if any "borrowing" of information was done to fill out the character of the other, it was the authors of christianity who did the borrowing. Luckily ancient Egyptians didn't take plagiarism too harshly.) Common sense and logic dictates that there is no possible way God could exist. There is no proof of him, although if anybody finds some feel free to let me know and i'll believe. And please don't feed me the line that we just need faith in him though we may not see or understand. It's obvious that the creators of christianity realized that their religion was somewhat ridiculous and that they would have trouble getting people to follow them unless they could be taught blind, ignorant, faith. But yeah, long story short, the son of God is not returning to this earth because no God exists to have ever had a son to have sent in the first place.
