Oh buddy, you clearly have no idea what you are talking about and I am not going to be the one to educate you fully on the MOUNTAINS of evidence there is that not only do aliens exist, but that they have been visiting this planet for quite some time and continue to do so to this day. I bet you are a really religious guy too, right? Well there is much more evidence for the existence of aliens than there actually is for the existence of God, yet I don't see scientist beating down the doors of the churches, synigogs, and mosques, demanding evidence for the existence of God.

Doesn't science contend that dark matter exists even though they can't prove it? How do they do that? It has something to do with deductive reasoning and common sense based on known facts right?

Regardless, I still stand by my statement but let me modify my statement so that it falls more in line with your precious scientific method.

I believe the the greatest thing that we need to learn about the universe is that intelligent life exists everywhere throughout the universe. That knowledge will have a far reaching impact that will change the course of human history for all time and will be up to that point, the greatest discovery of our time. Just taking into consideration what we know now about the universe, I believe that anyone that thinks that intelligent life only exists on earth is a fucking hopeless idiot.
