The notion that life somehow originated on another planet and then came to Earth via outer space holds a wistful obsession for many evolutionists. This is because:
- They have been unable to explain the origin of life on Earth, and even the ”simplest” living cell is now known to be unimaginably complex.
- As life has been found deeper and deeper in the fossil record,1 and so in older and older strata according to evolutionary dogma, many are now saying that there has not been enough time for life to have evolved on Earth; thus an older planet is needed.
Of course, postulating that life began on another planet does not solve the evolutionists’ problem of just how non-living chemicals could have turned into a living cell — it merely transfers it to another place.
Wanted — a planet just like Earth!
Conditions for life
The optimum place for life as we know it on Earth2 to exist elsewhere in space would be a planet with features just like those of Earth. These include having a star very like our own sun (an exceptionally stable star),3 being the right distance from its sun,4 as well as having an orbit5 and speed of rotation6 that would maintain a suitable temperature range, and hence fulfil the “Goldilocks criterion”—not too hot, not too cold, just right. Another essential would be the presence of liquid water—in living cells, water provides a liquid medium, necessary for amino acids and other organic molecules to mingle and react.7
Also needed would be an atmosphere that was non-poisonous,8 and which would also absorb or deflect lethal doses of ultraviolet light, x-rays, and gamma rays, as well as a magnetic field strong enough to deflect the solar wind (a stream of high-energy charged particles).9 Complex life forms would need oxygen to be present in the right proportion. Earth is just right for life.10
Mars
In the past, some researchers believed that Mars once fulfilled enough of these conditions for life to have existed there; however, many scientists no longer accept this. In particular, most now reject the claim that a small “Mars meteorite”, picked up in Antarctica in 1984, contained fossilised micro-organisms.11,12 And there are increasing doubts that Mars was ever as warm and as wet as thought, despite the claims of catastrophic flooding.

How interesting! I’ve encountered articles such as this in the past and this is a great refresher to them as well as an updater. Back then, the idea that Mars had water was being discussed, but here the issue is no longer in doubt and is discounted. So is the idea that spores could navigate through space and live, which they couldn’t.
Back then, those issues weren’t settled in my own mind either, but today I can throw out those fictional conjectures with such solid information that life couldn’t exist elsewhere.
If it couldn’t exist elsewhere, it couldn’t “evolve” there either.
Now if we can only convince the silly earthlings that they didn’t “evolve” here either.
