Mars and Earth ...are apples and oranges.....Mars could have evolved differently.

This discovery is far more important than the news mediots realize. As you know, my degree was in geology and I was very impressed with how they used multiple pieces of evidence to support their conclusion.

I also note that by next week we will have the answer on whether the layered bed was formed in water (sedimentary) or simply acted upon by water. This is very important.

In my opinion, I think they are laying the proofs down one by one for explaining what I believe to be fossil evidence of life on Mars. That announcement (which I believe will eventually come) will shake the world.

I'm waiting for them to find an SUV!
Here's how it goes: Mars was the birthplace of humanity.
We evolved there, built a society, including SUVs. Greenhouse effect, global warming, evaporated the water, got to a critical point of heat, and *whoosh* there goes the atmosphere. What's left is a cold, dead stone.
Good thing some of our ancestors got away and came to Earth before it all happened.
