Are the Gospels Reliable?

This betrays flawed understanding of methodological naturalism. There is no reason historians could not conclude that someone died and returned to life if there was sufficient evidence for them to do so. Methodological naturalism entails neutrality on the existence of the supernatural. It does NOT entail dogmatic rejection of things because they have been determined to be “supernatural”.

Whether the universe had a beginning is a question that can be determined purely thru science. It just has not yet been determined.

An article that tries to establish thru metaphysical argument that the universe had a beginning is attempting to go beyond what metaphysics can accomplish. Philosophers should stay in their lane and let the cosmologists do their work in peace.
