I suspect the only proof I have that there is intelligent life in the universe is the fact they have not tried to contact us.

I can only imagine how we look when you view the Earths occupants from a distance. Humans may likely be the only species ever to know they are causing their own extinction and still do nothing to change that course.

I highly suspect humans are the only ones that will argue whether there is enough proof of their demise. How much “proof” does one need? Take global warming (or is it cooling this week?). Perhaps the earth is warming and perhaps we, the human race, are the cause of it. I am being generous with the “perhaps” but I am fairly certain that Ducks, Dolphins and the majestic Platypus have nothing to do with it. It is also possible that this global warming is a natural cause of events. We really don’t have much more than 100 years of documentation, so for all we know, the normal cycle of the planet is 250 years or so of hot and cold flashes.

With that said, there is certainly sufficient documentation that the planet is changing. There is also sufficient documentation that we are using up the planets resources at an expediential rate. I suspect that alone should be enough to seriously look at our behavior and make changes…just in case. Alas, it is not.

If there is no other life out there, not only does that make our plight even more tragic, it would be incredible waste of space.
