How do you explain the existence of the physical universe? Evolution? Every evolutionary model that I have seen postulated is not only unscientific, but anti-scientific, violating a plethora of the laws of science. It takes a far greater faith (and a blind faith at that) to embrace the theory of evolution than it does to embrace the truth of creation. No matter what area of science one examines, i.e. physics, biology, geology,etc. evolution is always refuted, and creation buttressed (if one is intellectually honest). "For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness; because that which may be known of God is manifest in them; for God hath shewed it unto them. For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse: Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. Professing themselves to be wise, they became fools." Romans 1:18-22
