Blues Man: The First Cause had to always exist (i.e. eternal) otherwise there would have been something before it to bring it about, so it couldn't be first if it didn't always exist (i.e. eternal). And if it didn't always exist then there would have been something else that caused it, so it couldn't be the first cause.
Ergo The First Cause must be Eternal
These are pretty simple statements because the logic is pretty simple.
