Atheist scientist Richard Dawkins is known for his bold, harsh attacks on religion, particularly against those who believe in the Bible. Fortunately, he's his own worst enemy.
Dawkins not only hurts his own cause by routinely insulting Christians and other theists, he falls victim to his own illogical thinking. On one hand, he states time and again that the creationist perspective of life being caused by an intelligence is hogwash, yet he's also expressed a belief that aliens may have seeded life on this planet.
So what Dawkins is really saying (besides making it clear that he's the L. Ron Hubbard of the science world) is that he's open to intelligence as a cause of life, as long as that intelligence is not God. And thus he reveals his true colors: He despises the very notion of God, and his reason for this, no doubt, is the one that's common in society: the desire for no moral accountability.
It's likely that many people have never made this connection between creation and accountability, have never realized that being the product of some higher intelligence means being accountable to that intelligence. Richard Dawkins, to his credit, has realized this, but has made ill use of that knowledge.
