The world will end if the earth we live on experiences friction between other planets that cause great shocks or a meteor shower hits the entire country like what happened in the time of the dinosaurs where at that time the animals immediately became extinct without a trace, if the disaster caused by floods or forest fires I think it will not cause the world to end because the entire world is very vast and technology is increasingly developing so they will try to prevent natural disasters.
If you look at the flashback of the dinosaur story and imagine it as a terrible apocalypse, what is certain is that God's power will be very influential at the end of time, hopefully we will be among those who are loved by the creator.
I do really believe that there's a creator on which there's no way that we would really be that existing without any reason or the ones who do created us. I do believe on dinosaurs too but i dont believe that we do came from apes. 
On this world then there would be different of religions that do exist but we do share up on the same God, although there might be some differences in beliefs but one things for sure that there's someone who do created humanity. Speaking about on ending of this world then i do believe into this one. We do have a bible or whatever that other holy scriptures from other religion but pretty much sure that we do really that having that talks about ending up on this world on which purging into those sinners and would be having that new beginning.
Those are scientific fallacies about those evolutionary theory which postulate that humans came from apes and other higher life as far as am concerned Those are nonsense it holds no water all religions no matter the difference that exist in the world believes in a creator which implies that God exists and that one day we will go back to him so one day the world will definitely come to an end
We do know that scientist are athiest on which everything could be explained through science and there's nothing we can do about it. There's always a reason on why this and why that when it comes into this aspect. There are just that those individuals who do have their own perceptions basing up on what they do believe neither on religion or simply with their knowledge into things.
We do know that we do exist not on just on coincidence and even myself dont really believe out that we do came from apes or having that evolution. Somewhat there's no one could be able to tell on whats the real thing after all.
