Life originated from Mars – Myth or truth?
If this unusual fact is true, we should all be called Martians instead of humans and our home planet should be Mars instead of Earth!
Steven Benner of the Westheimer Institute of Science and Technology made this argument at an international conference of geochemists that initially, Mars presented a more welcoming environment for life to initiate as compared to Earth.
As per him, “The evidence seems to be building that we are actually Martians; that life started on Mars and came to Earth on a rock,” to which other scientists generally agree too that earliest life form was just a single RNA molecule that further replicated into other RNA molecules having the same template.
All that lacked was some scientific evidence about how this RNA strand came into existence.
Furthermore Benner talked about another intriguing phenomenon to understand life and its origins known as “the water paradox.” Interestingly Earth was all water when it came into being, although that’s an essential requirement for life sustenance but the characteristic polarity is corrosive to RNA and DNA which are bipolar in nature. Thus coming back to the question, how did life ever start?
Benner can’t speak for sure, but certain evidence represents an oxidized mineral form of the element molybdenum and the mineral boron keep organic material from turning into tar, this may be the sole requirement for life to start. These two elements were not found on Earth that early in time due to lack of oxygen and high moisture, but Mars had the conditions 180 degree opposite.
“It’s yet another piece of evidence which makes it more likely life came to Earth on a Martian meteorite, rather than starting on this planet,” Benner added.
This claim might also solve the water paradox because back when life was originating, Mars had both arid land as well as areas covered by water.
Although Benner’s talk did not provide a convincing argument for life’s originating from Mars but he did gave enough evidence to support his theory.
Nonetheless he’s glad for being an earthling than a Martian as he said, “It’s lucky that we ended up here, as certainly Earth has been the better of the two planets for sustaining life………If our hypothetical Martian ancestors had remained on Mars, there might not have been a story to tell.”
