Do you think aliens in ufos have visited Earth? (And all things UFO)

I'm 100% with Optimus on this one ^.

It's one thing to passively search/monitor for alien signals, but I think it's monumentally stupid to actively send out signals....effectively inviting a search party to a planet that we ourselves are captive on, with no means of leaving. I can only think of 1 good outcome from that, but about 99 ways to regret it.

I mean what should we be afraid of?

If they can travel to other planets, surely any minerals or other natural resources available here are also available on one of the trillions of uninhabited planets out there.

I can't imagine anything we have here that they would want to take from us that they couldn't get with much less trouble somewhere else.
