What do Christians believe in terms of E.L.E's (Extinction Level Events)?

If you only wanted the perspective of unbelievers, why did you ask christians. You say you want answers from christians but you don't want to hear any reference to where we get our answers from or what they say. Your whole question is predetermined to get the response you want. "I would also appreciate this without referencing from the bible if possible...". Well sorry. If you want the response from christians, you're gonna have to hear it from the bible. That's where we base our beliefs. Or hadn't you heard?
