I haven't run into any evidence, solid or otherwise. I do think it might be interesting to discuss what sort of evidence would be solid and convincing.
But, the point I sort of was trying to make is that maybe one day (perhaps it's already happened) some guy or guyette may experience something incredibly significant, important, unbelievable-- maybe even earth-shattering (sounds like an orgasm, doesn't it?) and would not know whether to even mention the extraterrestrial encounter even with solid evidence or proof because of the negative consequences he/she might experience. I see it as a terrible dilemma for a person to be in.
Like trying to convince people the world isn't flat? You keep trying to explain/demonstrate your idea/theory until you prove it. That means putting yourself out there for all to call a fool.
