If those things had not happened, so that life would not have evolved to its present state, the atmosphere would not have so much oxygen. The oxygen is due to our close cousins--the plant kingdom, who are as highly evolved as we are. It would be high in methane and CO2, although it might have water vapor.

Considering cosmic distances, I don't think you need worry about them sticking a straw in your ear.One would hope. I can't say I would want to bet the future of humanity on that hope.

Too many variables to validate "Fermi's Paradox.
Distance is one of the bigs. If a race is radiating into space and they are further away from us in light years than the number of years they have been radiating, we will never see them.

they may interested in us in terms of colonization and harvesting of available resources.The trip would take more energy that they would harvest.

I just don't think we need to waste money trying to contact them.Why? To find out we are not the only tool building race in the universe would be most profound!

We can't communicate with the animals and plants we evolved with - why would we be able to communicate with beings we hadn't evolved with? SETI is not looking to communicate. All we are doing is looking for that narrowband carrier that indicates a non-natural origin.

Yes it would, but what is the most you are willing to spend on profoundness?
