Phil,
I have no arguments against your points here but, I do have a few questions.
With all due respect and hope that I am not too far off base here.

Based on thousands of photos of Mars it seems to be a lot like Earth less the water and growies.
Although there are a lot of places here that do look exactly like Mars.
Isn't it possible for igneous rocks to become metamorphosed into rocks that might be from past oceans on Mars?
 
One of our probes definitely confirmed the presents of Glauconite and Albite on Mars.
these are also found in Earths oceans. So, I tend to believe a lot of what our scientists say.
Even without extraordinary proof.
 
To me there are theories being postured that are far more in need of proof than the fact that Mar's may have life. Such as.
.
The Moon was created by a giant collision with earth?
What? The Moon is nothing like Earth and what about all of the other planet's Moons?
Did Saturn and Jupiter get hit as well? Wait! How would that work? Aren't they Gaseous? What would it have hit?

But the most Crazy theory is that ALH84001 is even from Mars at all.
It does not match any of the other SNC's in either Mineralogy or Isotopes. Yes, it has some like minerals but that should not come as a surprise.
And Yes, they say if the O- isotopes match, that is diagnostic of origin.
Problem is that ALH84001's O-isotopes does not match the others. So, how could it have the same origin?
Please explain that one?
It was first classified as a diogenite because it is very much like a diogenite (if it looks like a duck) . But for the some reason it suddenly became a new Martian meteorite.
It may well be from Mars but, if the isotopes don't match the others then how could it be? Usually Isotopes rule. Don't they?
I am asking because I would like to know not to disrespect anybody here.
Seems to me it may be from a different planet?
Carl
