Where as some one arguing against me may see that data help prove them right.
But certain evidence is indisputable in one direction. Like, let's say that one of the Mars Rovers discovered skeletal remains. That would be indisputable proof that life once existed on Mars. You couldn't possibly argue against it.

Like the people that say look at this calculation that shows the statistical likely hood of advance aliens living in another solar system. Some would say, Wow this proves aliens exist; even though its a very very small number there are so many solar systems that there must be millions of advance life out there. Where as I look at it and see the tiny likely hood, read about the solar systems that are within the 10's or even 20 thousand light years to earth, read about how basically none of them could sustain life, realize that there would be no life anywhere near us either talking statically or probably. So even if there was plenty of advance life further out than that, they would never know we existed and even if they magically did, they would never get here within anything remotely close to our life time even if they were traveling at the speed of light.
I agree with that. Even if let's say they are monitoring for radio transmissions, just like our SETI programs, we have only been transmitting radio waves for about a hundred years or so. That means that even by the small chance, races are out there looking for radio signals around the Earth, the only ones who would have detected us by now would be the ones within a 100 light year radius. So assuming the nearest system with life is 10 or 20 thousand light years away then there's no way that we have been detected yet. But like you said, "even if they magically did", they would have had to have left their home planet before humans existed to get here in our lifetime.
