Wow. Crackpot much?
Who's to say DNA evolved here on earth?!
All we know for fact is that at a point there was no life. Then there was life. Something happened. DNA either manifested itself here or it was brought/ended up here from somewhere in the universe.
DNA is a series of amino acid chains. Amino acids can occur naturally under the right conditions when the necessary molecules are present.
While the idea of little bug eyed monsters intervening on our behalf is appealing to some, there's no evidence for it whatsoever, while the naturalistic explanation does have evidence.
The alien theory is somewhat more realistic than invisible-sky-man-virgin-humping-Jesus-daddy, but not by much.
80% of the ingredients for life is H20. Are you saying earth is the only place with water that can support a stable life form?
Who are you talking to? Are you arguing with yourself?
We require water. Some bacteria require methane. We're carbon based life forms on Earth. But there may be silicon based life forms elsewhere.
If so, what are all the radio signal that are aimed right at us?
Might want to take a course on Astronomy. There's a free on on iTunes University, and there should be one on MIT Open Courseware or Berkeley.
Radio signals are just a narrow band of energy, part of the same spectrum in which we find visible light, X-Rays, Gamma Rays, etc.
They occur in nature. The fact that we can produce them artificially does not mean all signals from space are manufactured by beings.
Pulsars, Blasars, Quasars, Neutron Stars, Black Holes, Supernovas, etc. etc. all give off various frequencies of detectable energy. If you want to see what the radiation from the big bang looks like, turn on an old television set that shows snow when it has no channel active. Just under 10% of that noise is the background radiation left over from the big bang.
SETI has been analyzing signals for years with no success yet. While there may be other civilizations out there, the chance that any one detectable radio signal out there is a civilization would be very slim, given the technological window when radio waves would be used by any given civilization.
Why are there pyramids on mars?
There aren't any.
What are the towers on our moon?
There aren't any.
I suppose you could have tried making those rather silly claims back in a time before we had high resolution images of both mars and the moon... but you didn't.
There are no pyramids or towers.
No green cheese. No canals and no little green men set on impregnating our females.
Too many things point to us not being alone. Either in the past or right now as well.
We either are or we aren't. The only sign of life we currently have is a meteorite that originated on mars and has microscopic fossils indicating the presence of bacterial life far in the past. And it took a decade of going back and forth over the data until they could say "We're *almost* certain."
Not to mention every religion on earth says something about people coming from the 'heavens' and enlightening man kind and bringing life. What would ancient primative peopl call another form of life visiting earth? Gods.
People have called snakes gods.
Birds? Gods.
Wolves? Gods.
Trees? Gods.
Somebody somewhere is worshipping something pointlessly every second of every day. It doesn't make ETs or Jesus any more likely to be watching over us.
