Topic: Methane found on Mars. Biology or Geology?

not trying to "rain" on your parade but recent observations of the Earth's upper atmosphere seemed to show a nearly constant bombardment by millions of microcomets. One rogue scientist has long proposed this as the source of Earth's oceans. While scientists don't necessarily buy thattheory wholesale they are giving ground on his interpretation of the phenomenon of microcomet bombardment.  

I have heard of it, but what I heard made it appear very unlikely.   Has there been any independent confirmation of the existance of the "micro-comets"?  Last I heard there was not.  Mars due to its much thinner atmosphere (and the moon with none of course) should be showing clear indications of surface impacts from them, indications that I have not heard of.  

Myself I still don't think that there is any clear indicator of life past or present on Mars.  At best some things that suggest the possibilty only.

There was independent back up for it happening here. [The micro-comet bombardment] not necessarily the cometary origin of earth's water] But that does not mean that it happens to mars. Anyhoo    I was just throwing up possibilities that might come out in debate.
