Amino acids in meteorites are remains of life
Many people think amino acids found in various meteorites are abiotic, produced chemically by their parent bodies (asteroids).

That is not true. Take Murchison meteorite for example. It contains not only excess of left-handed amino acids, but also fossilized cyanobacteria and fat cells as shown below:

Biotic amino acids:
“More research found that some amino acids were present in enantiomeric excess,...”
Enantiomeric excess can be produced only in biology, as non-life method produces only racemic amino acids, which are even handed (50% left handed, 50% right handed).
