I know this is crazy base on what people post at the Internet now a days.
Do you actually believe in aliens?
Basing on people's posted video I would say yes what do you think guys? I hope I am not just the one who believes in aliens.
Anyone who doesn't believe [intelligent] life exists other than on planet earth is an idiot or religious (thus, an idiot). With the number of stars and planets revolving around them.. The conditions for life to emerge will inevitably occur.. For the religious people, I like to ask.. "Why did god create the entire universe if the only space that would be actively used by his creations was Earth?".. It's grandiose to suggest that (if god is real) he created an entire universe for a single creation on a single planet, in a single solar system.
The better question is, "have aliens visited earth?".. Now, that answer is debatable. You'll get everything from 'no, just secret government projects, no aliens' to 'lizard aliens control the governments'.
Who's to say that it's even possible to travel from one solar system to another in a timely manner? And, if it is, and an alien race is capable of doing so... Why would they care to visit some backward redneck planet at the edge of the solar system filled with self-indulgent, self-important bigots?
Why not? Problem with believing aliens inevitably exist out there is that there will be all kinds of them. Those that would avoid us and those that wouldn't. For whatever reason we might not even understand. As for ways to travel between stars we can already think of some. Generational ships for example. May take a long time to reach the destination but should work. So maybe the question is why haven't we seen any of them yet?
