Clarification: What if...DNA was thrown into a primordial soup on various *planets* Not necessarily humanoid.

DNA...created by an algorithm on a computer software program.....maybe we are AI. After all, both Edward Leedskalnin and Nikola Tesla theorized (and proved, some may argue) that all matter is actually tiny individual magnets. Both observed that on the quantum level, magnetic fields have a unipole, double helix shape... double helix... hmmm, what else is shaped like a double helix??

During John Von Neuman and Alan Turing's work to make Colossus during WWII, one of their scientists was able to create a completely autonomous 'organism' in a probability matrix (binary cyberspace). It learned, evolved, made decisions, etc.

Mathematically, it's all possible.
