Where did thar first cell come from? How?
From a statistical/biological standpoint, simply I M P O S S I B L E!
But religious, of the scientific kind, have a more over-the-top, completely ridiculous view of how, given enough TIME, that first cell just magically APPEARED..
As much faith is required to believe this as to believe in the tooth fairy (Well, at least I magically got REAL MONEY from the tooth fairy.)
