Most people understand that sexual lust has to do with propagating genes. Copulation in nature tends to lead to reproduction and so to more genetic copies. But in modern society, most copulations involve contraception, designed precisely to avoid reproduction. Altruism probably has origins like those of lust.

Religion is nothing more than a useless and sometimes dangerous, evolutionary accident. Religious behavior may be a misfiring, an unfortunate byproduct of an underlying psychological propensity which in other circumstances is, or once was, useful.

If you have ever wondered why scientists like Popper, try Medawar's exposition. Actually most Popperian scientists have probably never tried reading anything but Medawar's exposition.

God is the answer to all of those "How must it have come to be" questions.

It could be that at some earlier time, somewhere in the universe, a civilization evolved by probably some kind of Darwinian means to a very, very high level of technology- and designed a form of life that they seeded onto perhaps this planet. And I suppose it's possible that you might find evidence for that if you look at the details of biochemistry, molecular biology, you might find a signature of some sort of designer.

Creationism: God's gift to the ignorant.

There is an anaesthetic of familiarity, a sedative of ordinariness which dulls the senses and hides the wonder of existence. For those of us not gifted in poetry, it is at least worth while from time to time making an effort to shake off the anaesthetic.

But we can recapture that sense of having just tumbled out to life on a new world by looking at our own world in unfamiliar ways.
