I have seen no evidence of a god personally, no. But there are many people who do claim to have personal experiences of god. They could be lying, they could be deluded, or they could be mentally ill. Or they could indeed be right. I find the latter possibility unlikely, but I can't rule it out.
In particular, I find it interesting that many eminent scientists are able to retain a belief in god. This doesn't prove anything, of course, but I find it curious that people who have based their lives' work on empirical enquiry into the world around them should cling onto a view that appears to have no basis in empirical evidence at all. Many of them believe that science cannot explain all aspects of "creation" and the natural world. They may or may not be right.
I am not arguing for the existence of a god, by the way. Merely that I'm not sure I agree entirely that there is no evidence that might point to a god. I think there are many things that remain unexplained.
And I believe that some atheists have closed their minds to all possible "evidence" of a god, should that evidence ever be presented. I recall seeing a TV report years ago about a study on prayer, which appeared to show a positive effect on patients who were prayed for, even when the patients didn't know that they were being prayed for. I don't know what the merits of that particular study were, and the methodology may have been deeply flawed. I found it an interesting subject, but my father proclaimed it to be nonsense and switched to the other channel - he had made up his mind before even listening to the report, because it contradicted his deeply held belief in the notion that prayer could not be effective.
To some extent, I think that religious people and committed atheists can filter out the "evidence" that doesn't suit their viewpoints.
