lol lol at some of the posts I read.
At one time I thought their may have been UFOs visiting Earth, but now I'm not so sure. I think if ETs were visiting our planet, they would have made an appearance by now. However, I do believe there's life somewhere out there. The universe is forever expanding, so how could there not be intelligent life forms out there?
Scania, as far as I know, there is no life on Mars and there never was bacteria found there. I think what you may be referring to, and I may be wrong, but you're thinking of the fossilized bacteria found on Mars. At least that's what scientists think it is. That's what they found, not actual living bacteria. I do think at one time Mars was more than likely a warmer climate with water in it's distant past, so there may have been some kind of primitive life there.
While we're on the subject of Mars, I wonder if we're running low on resourses here on Earth. We want to colonize Mars and turn it green, so it can support life. Why the need? Astronauts went to the moon nearly 40 years ago, and decades later it's still the furthest human beings have gone. The next obvious place to go is of course Mars. I think the discoveries we make on Mars could reshape the way we think about our place in the universe.
The money we're spending in Iraq which is a total waste, we could be using to do further research on Mars. I'd say going to Mars could range from tens to hundreds of billions of dollars. Now that I think about it, to put this in perspective, it's considerably less than what the United States has spent in Iraq.
