The non-God answer:
Naturally, somewhere in the universe, the conditions were right. Some chemicals in a primordial
soup with the right atmosphere, etc., came together to form a single-celled organism that could do all of 3 things: 1)
maintain itself, 2) reproduce, and 3) evolve.
Researchers and lab scientists on earth, however, have found many impossible obstacles …
a few are:
a) the existence of oxygen and the need for b) only left-handed amino acids, c) synthesizing
proteins, d) activating enzymes, e) ribosomes, f) an orderly mechanism, and f) much more.
Because no one has found the right conditions on earth, some scientists may appeal to an alien planet, and believe that life was brought or sent to
earth. You may hear the word “panspermia” in this context.
The God answer: God created life.
