The operative word: "SPECULATES"
The question is whether life is the exception or the rule.
Either answer will have implications that are awe-inspiring, if you are inclined to awe.
I can't wait for them to start core-drilling; I want to see whats under Martian soil.
For instance, the very hot and cloudy climate of Venus is likely to have developed after a runaway greenhouse effect, and the more we know about this the more we can understand some of the challenges caused by our climate change on Earth."
Interesting up until that point. I guess if the USSC can use foreign law, we can use interplanetary evidence to support global warming.
I'm no sure how we get to "very likely" from "30 years of exploratory spacecraft missions without finding anything." I'd go with "possibly."
If you landed a spacecraft anywhere on earth, you'd find life almost instantly.

There is a first for everything and as time goes by, I'm beginning to think that we are the first intelligent lifeforms........(but there are many, many days in which I question "Intelligent")
Where's Carl Sagan and his "bbbbilllions and bbbbillions" of planets when you need him?
That's a load of horsecrap. The first life developed under anaerobic conditions and would actually have died in an oxy/nitro atmosphere.
The life on other planets is just a single cell, not implanted yet.
"By understanding better how the climates of planets like Mars and Venus have evolved, we can understand more about climate change on Earth."
It's more unrelated political agenda seeping into planetary science.

I think life is the rule rather then the exception. I think life is a part of the fabric of existence along with space and time.
When you consider that there are over 100 billion galaxies each with around one trillon stars then there must be millons of worlds with intelligent life..
The earth is 5 billion years old, the known universe around 15 billion. That gives us 10 billion years of missing time.
We have found about 150 exosolar planets so far, all gas giants but within 10 years we will be able to detect earth sized planets. Within 100 years we will be able to go to the stars. As soon as we are able too we will visit planets around the other suns that we find.
It's impossible that intelligent life from other worlds is not here now considering the odds that within 10 billion years some races have not advanced more then 100 years ahead of us.
