well...firstly in terms of how long we have existed, we are merely a second on 24hr clock ( something like that)... so, it may be possible civilizations may have already existed well before our time or will exist after our time. in 6 billion years the sun will die, earth well before that. maybe we are the 100th earth like civilization with our technology to exist but we dont know it. its a suprise our earth has lasted this long. secondly, if you were an alien life form would YOU want to just come down and say hi? we are a violent and volitile society. we need more time to develop! and if you were an alien life form smart enough to travel faster than the speed of light etc, maybe they are waiting for the right time as an advanced alien race would actually use their brain and would not need the use of religion ( humans scapegoat for our existance )and are waiting for our development before we are made savvy to an interplantary federation lol. also...maybe time travel has already been possible...maybe our future has been changed ten times over. maybe the powers that be in the future took control of this and moniter it aka timecop? and if someone did comeback to say "hey its possible" im sure you could time travel just before he landed and execute him effectively "cleaning up" any "ripples". the brain cant comprehend this technology yet so until we do its speculation. also what if...WHAT IF... "aliens" are us? the "ufo's you see could be us time travelling...maybe we as an advanced human race, came back in time to give basic technology to egyptians...which could explian alot...to speed our evolution up. so that we dont end up dead in a couple of billion of years? whilst this is all speculation, and the arguments could be infinate, we wont be around to see any result, as technology to bend space and time, or travel to other systems ( disregarding the technology to create and build this, how would humans even survive a 12 parsec run with hyperdrive set to max is another issue haha) is all well hundreds of years away. we have alot to learn, humans need to evolve to another level to comrehend turning fiction into reality, but who knows. maybe tomorrow something happens to change the world?
