Why would Martian life be similar to that on Earth? About 4 billion years ago, when terrestrial life probably got its start, rocky bodies were flying through the solar system and slamming into the planets. These impacts threw pieces of the planets into space, and some of these pieces landed on other planets as meteorites. Ancient microbes might have hitched a ride to or from Mars on these meteorites. While in space, the surfaces of these rocks would have been sterilised by UV radiation.......

Life on Mars? How will it be like, if it exists?

Life' origin is still not known and science believes that life originated on earth. According to the article life might have landed both on Earth and Mars from meteorites.

Assuming life exists on Mars, DNA sampling on Mars will be watershed in the search for alien life.

Did DNA /Genetic code on earth evolve separately from that of Mars? Time will tell, in 8 years! Mars might evolve life at a future time, and maybe life will be more intelligent there than on earth in the long run.

Really? Scientists believe that life began on Earth?

What scientific evidence do they have to support that conjecture.

When you say scientists believe, you are speaking about the scientific community; not just a particular couple of scientists doing their own independant thing.

You can always find a couple who believe in anything.

I have never heard of the scientific community supporting a particular point of origin for life.

Our culture seems to favor a geocentric origin, the reasons for this are probably more religious, and mythological then scientific.

However the scientific community, to my perspective, seem open minded on the issue given recent evidence.
