Matter changes form all the time.
So I don't know how a materialist can deny the resurrection. It's matter changing form. If God intended a massive change later and wanted to let us all know then it'd be reasonable of Him to give us an example or two and leave a few witnesses of it so word gets around.
From Wiki Answers:
Matter changes with everything.
Example: breathing, your lungs change the oxygen into carbon dioxide, and plants change it back into oxygen, that's matter changing. Burning coals, the fire changes the carbon in the coal into carbon dioxide, and the plants do their photo synthesis bit and change it into oxygen.
Another Example: sand is heated until it becomes molten, then it cools to form glass.
