      As of now, there is no scientific evidence that the world will blow up soon or that aliens exist.

      The Sun will reach the end of its life about 5 billion years from now. That’s a very very long time! In fact, humans might be extinct by then!

      5 billion years in minutes = 5000000000 x 365 x 24 x 60 = 2.6 x 10 tothe power of 15 minutes….I think that’s quite some time!
      No idea when aliens will invade, hope they’re friendly.
      We could survive the sun roasting the earth if we’ve found new planets in different solar systems to live in by then.
