Have anyone seen creatures or objects from other planets or galaxies?

I haven't seen anything strange, but I came up, or perhaps been influenced, but I know I remembered thinking to it for myself. (Trying not to offend anyone) But I came up that (using those ancient alien evidence) that we humans are nothing but experimental beings by some great civilization. I say this because, the beginning of UFO citing of the modern Era began during world war II. The German army themselves began creating flying saucers when their soldiers encountered sightings. Similarly the allied forces also reportedly encountered some. So basically the reason for the sighting increase was, that great civilization has been observing us, and just became more interested when we had this great wars, perhaps they were here in WWI as well but we just didn't see them. Also, the sighting increased some more after the launch of nuclear bombs, experimenting as well as the real harsh bomb in Japan. For that reason in increase, the great civilization became more interesting on how we humans have developed such devastating weapons in a short period of time. But who knows I could be wrong! It is just me being a thinker. Anyways, life does exist in space, maybe no proof of intelligent life but bacteria etc. perhaps exist. Research on the tardigrade. It is a microscopic animal with 8 legs that can survive in very VERY harsh conditions, more harsh than archae bacteria here on earth.

Yes! I don't it was a alien or something else but it seemed not from this planet. I was just walking on the street when suddenly a Green Object fell down. I was shocked and frighted as well. I went near and saw a Green light coming out of it. Then suddenly it was all bright. INTERVAL....I was watching "Green Lantern" in 3D..lol

I have not seen one but that does not mean that they aren't out there.

Yes, there are stories and films about that. I have heard and have seen news in the newspapers some times about UFOs. But, honestly speaking, I have not seen any in the sky with my own eyes so far. That would be quite interesting, and exciting.

No, I haven't seen one. though all i know is they exist... only in tv shows and in movies! who knows, one might really state here they have known or read some facts saying some people have seen or experienced it, right?
