Without siding on either side of the argument there is the problem of landing a small lander on a planet sized object especially when aiming from
Earth to Mars. Imagine a probe coming the other way. It could get lucky and land in Manhattan and proof of life (of a kind) would be pretty
conclusive. But if the lander came down in the middle of a vast desert or salt flat or say somewhere in Iceland which has some amazing volcanic
landscapes, then the lander could trundle around for ages and not spot anything remote looking like life, or even miss life because of the time taken
to take a photo, or the sample taken was an inch to the left from something that would prove conclusive.
That they've managed to land Curiousity and get images back, and it seems to work is nigh on miraclulous, It's pretty demanding to ask it to land in
just the right spot to find life, signs of life, or an alien in a baseball cap waving a Yankees flag grinning and saying "Hi Folks".
Give the people time to explore, let's hope they are honest with us.
My own view is that if they do discover life, current or past on Mars, then it will show if two bodies in the same solar system can support life then
the likelihood is that the Universe is teeming with life on every last rock where it might take hold. Whether civilisations develop from that life is
another matter altogether.
