The world will come to an end eventually. Without a doubt by the time our sun becomes a red giant, our home planet will be entirely devoured by the sun's expansion, however, I wouldn't be surprised if life on Earth went extinct before then. The religious originated signs and warnings of an apocalypse are so blatantly fraudulent, because of the logical fallacies they withhold and obvious origins.
"Signs will appear in the heavens, the sun will be darkened and the moon will not give its light, the stars will fall from heaven, the sea and the waves will roar and the powers of heaven will be shaken (Matt.24,29; Mark,13,24-25; Luke 21,25-26)."
These supposed signs are just natural events. Shooting stars and comets, eclipses, meteoroids, and tsunamis and earthquakes. When primitive men saws these thing, they theorized why. They were signs of the end of the world was their conclusion, because that's how it appeared to be. This is precisely like how the hypothesis that Earth was flat originated, because it appears that way from their limited observation and knowledge. Most of the other signs such as the seas will turn to blood red most likely originated from folklore and mythology.
