Sorry Cowboy, I have to agree with ElNono on this.
The odds that one cell could change are so highly improbable, but when you throw in the mix of billions of star systems, billions of years, and countless molecules, etc, something remarkable can happen. Like the Poweball, but on a larger scale. The chances of any one ticket winning it is so ridiculously thin, but when you contemplate the hundreds of millions of games played, someone eventuality wins.
I am a believe of both evolution and intelligent design. I believe a higher power, may it be God(s) or aliens, had an influence on the natural development.
