When and how do you believe the world will end? assuming it will

I believe there are many different scenarios that can happen where the world could end, such as a rogue black hole drifting close to our system, an asteroid hitting our planet, a virus evolving and spreading at a fast rate, nuclear warfare, etc. If none of these things happen then in several billion years time our sun will turn red and swell up to engulf the Earth and all the other planets in its vicinity.
