Young-earth theories

Hi all,I stumbled upon this site recently: http://www.ridgenet.net/~do_while/sage/Which is the site for "Scientists Against Evolution." They make the claim that the earth is in fact not billions of years old, and base it off reasoning such as:Continental erosion
Sea floor sediments
Salinity of the oceans
Helium in the atmosphere
Carbon 14 in the atmosphere
Decay of the Earth's magnetic fieldNow, I have nothing more than surface-level of knowledge of evolution, so I would like to hear some thoughts and opposing arugments for these theories so I can see two perspectives.thanks!
