Is it dangerous to investigate UFOs? Yes I definitely think so, we don't know who all is involved with them, I believe they have humans working with them here or they even have human hybrids here. I was going to go to one of the local UFO meetings in one of the nearby towns and I was going to park a block away and walk over there, thought I could tell them a few stories. Work happened and could not go, and then read on their web site that 2 of the members were abducted after leaving the meeting or the next day something like that, so yes I think its very dangerous.
Trying to look for them on other planets is just pure silly, is it not much more important to make contact with the ones here first.
So what if you do find out where they are hanging out here on earth, what would you do then, you cannot sneak up on them, they are way too advanced for that. They could just be demonic entities, we don't really know, although I think most of us want to believe that their has to be an intelligent life out there somewhere, or on earth, after all we do see a lot of mile long UFOs here, so that means they are here.
