Or you know appearing on mass to all humans at regular intervals so there would be no doubt to his existence.
Or revealing some truth that we could not have figured out at the time (like complex math), leaving a few angels behind to perform various feats (we could still have this debate then, but it'd cancel out some religions), allow some people to still perform miracles, etc.
...2 bears...
Some dude in the bible was walking along minding his own business. A group of "little children" ran up to him and began teasing him about the lack of hair on his head. He cursed them in gods name. God sent 2 female bears to charge out of the woods and those bears managed to kill 42 of the kids (no mention of how many kids in total there were). Wonder if these (innocent?) kids went to heaven or hell after that. The dude continued on to his next destination after that.
Done by an artist who has no idea what bears look like:
Theres only about a dozen kids in this one, but it more accurately represents the bears:
Don't ask me about Jesus damning a fig tree. Seems strange to me, besides, figs are good.
Jesus was actually fond of figs. In the story where he damned one (a specific one) he had walked all the way over to the tree to get its fruit because he was hungry. He found the tree covered in leaves and it was supposed to be bearing fruit, but for whatever reason (I blame god) there wasnt any. Jesus damned the tree in his anger for its insolence. It doesnt say whether god sent any forest creatures out to maul the tree, but I'd assume that he did.
Bonus verse:
Behold, I will rebuke your seed, and will spread dung upon your faces, even the dung of your feasts; and ye shall be taken away with it.
And here ends the lesson.
