Origin of Life (Introduction)

A Mars meteorite from the 1990's was said to suggest bacterial life at that time. Re-analysis 13 years later supports the suggestion. Magnatities are seen by new techniques; and resemble those on Earth. If true, Mars had life 4.5 billion years ago.

> Not at all. If the universe is fine-tuned and coded to produce life, whenever it can happen (Mars 4.5 billion years ago), it fits my theory. The sun put out less heat (30%?) at that time so life had to deal with a very cold climate and may have been an extremeophile, which also supports my theory that a designing intelligence simply wanted to produce life through the construction of this universe; allowed, by planning for evolution of universe and life to both occur, kind of fitting Frank's process thinking. The Earth turned out to be the ideal spot. Did God know it would finally be the Earth: perhaps and perhaps not?-You see, the problem is that the converse position can be drawn with the same data... it wouldn't prove anything. If it turns out that life is common on any planet like ours--that's all it really means. -You've talked about a probability limit. I'm going to get a little aggressive here:-1. What is the number of this limit, and what reasons/systemic justification do you have for positing this number? -2. What are you comparing against? Meaning, if you have a probability limit, you have to have a system of measurement for it (or probability cannot be used).-3. What are your assumptions taken in support of 1 and 2? -4. Why do you think the assumptions are reasonable? -5. How confident can we be of this limit? (This part may shake out as we grapple with all of this.) -6. This question ties in heavily with 1 and 2. You have brought up Bayesian ideas somewhat recently--anytime there's a contingent probability. Considering that many contingent probabilities are misleading either due to current ignorance, why do you rule out discrete probabilities? An illustration here might help:-If you cut the skin of a healthy human adult, their blood will clot.
If you insert a sperm cell into an egg, you will have a stem cell. -How do you separate deterministic from the contingent in biological systems?

\"It is, brahmin, because of attachment to views, adherence to views, fixation on views, addiction to views, obsession with views, holding firmly to views that ascetics fight with ascetics.\"
