but, what if the conditions for life are different for different civilizations?

thats a good point, and yes possible, but how hard is it for matter to assemble its self into self replicating life, is my point, honestly life is just a pattern that self replicates and evolves enough to be intelligent and then finds earth, you could arugue that stars are just as alive as a tree is

Even if the conditions for life were extremely hard to come by, it would be common in the universe. There are more stars that we know of than grains of sand on every beach on Earth. Given the # of solar systems within our universe, it's impossible to think that ONLY Earth has life, or will have life on it.
We still don't even know exactly how life on Earth formed, and many Scientists believe that the building blocks for life were brought to Earth by comets. Even if it was just a microbe, cyanobacteria produced most of the Worlds oxygen more then 2.7-3 billion years ago. Back then, the oxygen level was closer to Mars than it is now.

As for ancient aliens, there are cave paintings dating back to the Dawn of man of UFO shaped objects. A lot of ancient Cultures believe in Gods that came through holes in the universe (All over the planet btw, and they're all similar), and they all say that one day the "Gods" will return. There are Renessaince paintings depicting people staring at UFOs (And not comets/meteors, as they knew what they were and the art is done differently). And a lot of the ancient structures that were supposedly made by humans would be hard, if not impossible, to recreate today. The Puma Punku blocks are made of granite and diorite. The only thing harder then those stones are Diamonds, so they would need Diamond tools to carve the stones perfectly. To build the Pyramid in the time we think it was constructed, they would of had to place one block every 2 minutes for about 30 years. Not saying that Aliens decided to build ancient monuments, but it is possible that we have had help, or at least been loaned some tools.

As far as time travel goes, we're no where near being able to prove or disprove if it exists or not. We've barely descovered Dark Matter (Which is far more common then regular Matter), and we don't know shit about Dark Energy (Which is far more common then even Dark Matter). We've just barely begun to understand the Universe.

but theres no proof dark energy and dark matter exsist atm, its only a theory to explain problem with gravity, and to explain why the universe is still expanding, untill theres some solid proof it exsists, im not going to buy into it

man thats huge bs

ATM, theres no way to observe dark matter. It passes through normal matter without any reaction except for gravity, and it doesn't reflect or give off any light. We can observe its effects, because if its not there then our calculations for gravity are wrong.
They even had a possible detection of a WIMP with the LUX in 2009. They dont look at the data for a whole year, so they might have found something against this year.

Haha I think it's u who fail to realize the vastness of space, yeah your right the conditions for life are rare, but there are billions of stars in billions of galaxies. Astronomers have done studies proving it's imposible for there not to be other life in the universe. I've had my beliefs that there are aliens LONG before ancient aliens has been on tv or some ,as u say, "pop culture alien beleiving bullshit" has been on tv. This has been a huge debate for a long time and I think the shows they have today arejust proving it even further. They are trying to decensitise us now for when aliens do show themselvs openly. I bet u the next one they have on tv are present alien encounters or some

psycho it's a belief not a theory u believe there arnt aliens and I believe that there are. Some 30 minute special never made up my mind.

lmao and when exactly did i say aliens don't exist? what i said was you are stupid if you think shit like wormhole travel will ever become a reality.

you sound just like the ancient retards who thought flight was impossible

lmfao. you are clearly a moron if you think something as simple as flight compares to bullshit like wormhole travel.
