There is not a scintilla of scientific (measurable might be a better word) evidence for any explanation for the start of existence. All are ultimately matters of faith.
Some faith, however, is better founded than others. Undirected abiogenesis is one with any foundation. It is irrational to believe this.
The Judeo-Christian view is a faith with a strong foundation. Christianity, for instance, is backed by the testimony of millions whose lives objectively changed for the better by accepting its precepts. Those who followed these precepts have accomplished objectively beneficial things.
I said far earlier that our laws, science and the concept of free markets itself were discovered by men advocating Christ's teachings and are ultimately based on Christ's teachings.
Skipping over any discussion of "objectively", wouldn't the Muslims say the same thing? Or Jews? Or Buddhists? Or Hindi? Or Jans? Or Shintoists? Or Taoists?
And would you include the Moonies, Jonestown, or David Koresh's little sect in your sweeping embrace of Christianity's successes?
