OK since we now have seperate threads for religion and evolution let's add missing piece to complete current origin trilogy puzzle aswell - extraterrestials.
This is topic is to discuss everything related to ET's or Aliens with little to none colliding with religion and evolution. And if you think there can't be possibility for them think again! Science currently supports this idea - for starters have a look at how our Earth compares to other objects in universe https://www.youtube.com/watch?v=g4iD-9GSW-0
Still think we are alone? And there are plenty more related material out there approoved by science facts that shows our universe is capable enough to allow possibility not just for one Alien group to exist but for dozen more! So yea - let's get this discussion moving further!
I figure now they are just watching and waiting to see if we kill each other off.
I know I would not feel like communicating with us losers.
I think every time they have crashed here. It has not boded well for them.
I don't see any reason to believe that humans had any extra-terrestrial origin.
If aliens were here, we'd all be dead soon after their arrival. This is not the case, and so we can file ET away with the rest of the religious and paranormal phenomena.

This sentence is plain ridicilous! Unless they are less intelligent than us which would also prevent them from space travel to our Earth to begin with, any higher intelligent beings would either hide and watch us from distance or infiltrate in our midst but not destroy us! I agree humanity is really pushing it often but they will never push it to the breaking point where they will be asking for complete destruction of mankind - that limit is far from us yet. Just silly - with all our history, results and future possibilities - any sane being would let us continue existing without second guessing and maybe even join us + help us.
The best thing to do is put yourself as the alien. Say that humans are the aliens, as they may well be.
Some questions need to be answered:
1) A colossal amount of technology is needed for space travel, and even more so for very long distances. A huge amount of energy is also required. Why invest all this ? What do you expect to get out of it ? What is the purpose of it ?
2) Say that humans are the aliens, they land on an alien planet full of primitive creatures. What happens next ?
My thinking is: If aliens are traveling in space, they are looking for something they need, perhaps they've run out of resources on their own world. After all, why else would they invest all this into space travel ?
Some would say, well they want to explore, and help primitive civilizations all over the universe. I'm sorry to say that resources are limited, and they have no reason to help anyone out of the goodness of their own ... do they even have a heart ? No, there's always something they need in return. It may be plausible that they would want to trade, but why bother, when they can simply take ?
Or maybe they want to just say hello, or hide and spy on us. But, that just doesn't seem likely calculating the investment. It would take them a very long time to get here even at the speed of light. Also imagine hitting even a small object at that speed. And what would they eat, and what would power them ?
If I were an alien, I would do one of two things:
1) Make a massive mining ship. Travel to planets that are uninhabited or only slightly so and get the resources we need. Fly home and unload.
2) Make a massive battleship. Travel to inhabited planets and deal with the inhabitants making way for mining expeditions and maybe even colonies if it is habitable to us aliens.
There is a technical third way:
3) Make a recon ship. Travel to planets and survey them for minerals and habitability. This is dangerous tho, and the ship will still need to be large. If you come up against resistance, you're as good as dead. Surely the aliens have developed less dangerous ways of surveying planets from afar.
Take a look at what happened with explorers here on Earth. What happened when ships landed on foreign shores ? Yes, I guess things looked good for a short while, but then things got ugly.

Or they have a totally different morality than ours and just get from our planet what they want. DOn't make the mistake to humanize possible aliens, they are most likely not humans or even humanoid, this is not Star Trek.
"Choose the nearest star; decide how long you're willing to travel, how fast you will need to go to get there in that time, what you will have to take with you, and how many should be in the crew. Make it a one-way suicide mission if you wish. As a final step, calculate the kinetic energy that must be imparted to the spaceship to get you there in that time (one half the mass times the velocity squared.) I suggest you stay away from the relativistic limit; it complicates the calculation and won't help you anyway. The good news is that you will then sleep secure in the knowledge that UFOs from elsewhere in the galaxy are not subjecting humans to hideous experiments." --Bob Park
It seems to me that if an alien race had a mostly-viable means for interstellar travel and anything like a human psychology, you could almost guarantee that some of them would find a reason to take to space.
Early human explorers spent months or even years in cramped wooden vessels, knowing that one bad storm could mean death, relying on an unreliable power source, with limited food and risking a beating from any natives if they managed to make landfall. Some of those who came home were disfigured from exotic diseases, yet more went.
I know space is a lot bigger than the oceans, even allowing for differences in technology, but there may be mitigating factors. The aliens may be running from trouble at home; they may be very long-lived, or have found that faster-than-light travel is possible; they might naturally live in space, lazily drifting between stars; or they might simply be both more advanced and more curious than us.
Visits would be less likely if they were hostile - it'd be easier to attack from afar using their technology of choice. If they had good radio receivers and could decipher some of our scientific documents, they might design a super-virus to render us (mostly) harmless. How much energy would it take to launch a capsule containing a few milliard virus particles?
Alternatively, they could troll various websites and stir up enough trouble to keep us fighting amogst ourselves, or better still, provide such stimulating blog posts that we all stay in front of our monitors and slowly atrophy.
