Why? WHO is your designer? Evolution by design is not 'pro-life'. Evolution by design ignores the 'soul/spirit intellect'. Evolution by design is an international salute to the Creator. But hey, each soul/spirit intellect that chooses to take this flesh journey does have the God given right to posit their possibilities.
I am quite sure you will posit some very intellectual words, but I am going to go out put straw around my potatoes. later
If you knew that, why did you ask by what authority I do it?
