I read some of the refutations from the first website.
And?
Did you see the streaming video? What are your views concerning the polonium halos.
That they can be formed over longer periods of time under specific geological conditions. There are credible hypothesis proposed, none of which assume an instantaneous creation of granite in a young earth. There is no evidence for such an even, only a
tiny mystery in the formation of polonium halo's (which only means that our knowledge concerning these halo's is incomplete). It's the same old tired deadbeat God-of-the-gaps explanation, personal incredulity neatly packaged in a physicists wrapping. Gentry is using a
normalised physicist's explanation without considering the specific geological processes at work and explicitely excluding al explantions that are evidence for an ancient earth.
This article on the NCSE website should shed some light on the issue.
