The bible explains it
well, of course it does, superficially at least. But, the way I look at the world, The Almighty doesn’t lie or deceive, and why should HE, because nobody would believe a liar, so if something is x years old, that’s when HE made it. If the oceans were forming 4.4 billion years ago, as far as I’m concerned it doesn’t conflict in my mind with being Biblical ‘day 3’
