See, now, evolution isn't technically a religion :}~. Sure, some people follow it religiously.
So...if the only purpose of dinosaurs is to give support to 'the follows of the religion of evolution'...um... *confuzzled*
And yes, we can 'see' a dinosaur walk. We have plenty of footprints (the museum I'm working at actually owns two footprint sites). See, as in, a living, breathing dinosaur walking down the street, no, duh. :}~ I don't really see what that question has to do with the rest of your post.
