Lets say for a second they have visited Earth, why have we not heard from them ourselves?

Do you think the Government is covering it up?

I think the world would be in too much of a shock if they were to be revealed suddenly, maybe the US keep it secret to be the first to harness it's technology, apparently the B2 Bomber was made via reverse engineering a Alien craft, apparently it flies with by Gravity propulsion.

Discuss.

no i dont believe in aliens and ufos

I believe in the vastness of the universe, and that is has got to be filled with something. I don't believe that our planet is important enough to warrant an interstellar trip.

While i believe there are other life forms on other planets i don't believe the "form" they've given them. This whole green, huge-eye thing.

I also believe in ghosts

Hell no......

@valen200

Why wouldn't it be?

We do pointless stuff like go to the Moon and plan travelling to Mars.

Why wouldn't an Alien be interested in visiting a place with civilization?

Aliens yes, UFOs no!

I dont think life is as special and unique as some people give it credit for. I think there must be life on other planets and that its as normal as the sun rising in the morning.

no. I'm sane, thanks :)

@--OkeyDokey--

You saying I'm not?

At Artofangels-

Well, seriously we not really close to anything major in the galaxy that we know of. Yes, exploration is a cause that furthers it's own ends. We climb mountains, it is said, because they are there. Still, in order for an alien race to actually take an interest in us you have to assume that it is worth the resources to travel here and then start drawing patterns in crops or whatever conspiracy theory is en vogue.
