I haven't yet jumped over the fence to atheism and as of right now (until I'm given adequate evidence of macro-evolution) I am a deist.
Of all the things that amaze me, non-acceptance of Evolution is probably the greatest. Those who go in for a Young Earth, I can dismiss as deluded along with flat-earthers, the ether that pervades space and spontaneous generations.
Those who see religion as a philosophy with a narrative and all writings as "symbolic", I can live with - it could have been any -ism.
Christians (and other religions) speak of "having to accept the spirit" to understand. This is a travesty of logic - first you believe then you understand then you believe. So believing in Evolution without evidence is equally stupid. The difference is that the evidence is there to be found.
And what's the alternative? Man was magicked out of dust? All the animals were placed here but then they changed? Why? Why would some mighty being who understood exactly how chlorophyll converts light and water to sugar and oxygen make a mistake with the millions of species that have gone extinct? Or was it that conditions cause them to die out, whilst others, over millions of years, adapted?
Nobody gets given adequate evidence of macro-evolution (or as I call it, 'evolution') - they go out and find it. I suspect that there would be no point some of us here telling you anything about evolution. Start at the beginning, understand as you go along, reason why these things are so and why the supernatural has no need to exist, and does not and cannot exist.
Did I say "Welcome!"? I should have done.
