I think that you are posting drivel from a site written by a carpenter and mason worker from his home in Canada, which speaks volumes of the relevance of this site. Flew did not convince me at all in his book because his arguments were flimsy, mostly philosophic rather than scientific.

"Intelligent" design.

Never heard of the guy. So he changed his mind about god due to science. Did he have objective evidence that any god was real? Did the fear of death with no afterlife scare him?

Flew was a famous British philosopher of religion. As I understand him, his long-term view was that there is no evidence whatever that would tend either to verify or falsify the claim that God exists, so it is a meaningless claim. However, as science progressed he came to believe that it did provide evidence that would tend to verify it (along the lines of special design). But I don't think this was the God of popular religion.

Flew's arguments from his atheist days stand by themselves.

Anyone convinced by the watchmaker analogy doesn't understand evolution AT ALL.

"There is more and more evidence....." And what, author of said piece would any of that be. A little name dropping or citations wouldn't get you lumped into the "some people say" category of bullshit.

I remember reading Flew as an undergraduate philosopher. It seems he suffered from some mental debility in his later years. The Wikipedia entry gives a good summation:

I think Pink Floyd said it best,
“But it was only fantasy
The wall was too high
As you can see
No matter how he tried
He could not break free
And the worms ate into his brain”

Just another person with opinions.
He clearly changed his mind about what he believed, and gave in to fear.

Not unlike many, but no better than anyone else.
