Ironically, it takes "Blind Faith" to "believe" that the Origin of Life began with a "Big Bang", an explosion from nothing...
It takes "Blind Faith" to "believe" that the Origin of Species is the result of a "primordial ooze"...from nothing
It takes "Blind Faith" to "believe" that the complexity of cells and the multiplicity of species is the result of random chance over millions of years. The odds are astronomical. One conservative value is 10 to the 210th power for accidentlly-synthesizing left amino acids for one small protein molecule! Thats 210 zeros after it!!! DNA is a whole another game... the chances of the sequences arranging it self in the right sequence for just one cell is even more astronomical and thus doesnt become chance but rather an impossibility... and amino acids to arrange itself in the right sequence is out of the question. Thus requiring faith.
It takes "Blind Faith" to "believe" that Evolution is the reason we are here. Look around you! You were CREATED!!!
