Your life is just a simulation, it’s that simple. This question presupposes that Earth is something materially separate from consciousness. There’s an old riddle that says, “If a tree falls in the woods and there’s nobody there to hear it does it make a sound?” No, because there is no tree if no one’s there to observe and receive data of it’s reality through (5) senses. The question assumes Earth has its own reality apart from the people on it and it doesn’t.

For something like that to happen a collective consciousness would have to agree to that, and that would take place in what’s called the between incarnation state. A random event of that magnitude will never happen unless agreed upon, thus not making it random. This is a hard concept to grasp only because so many people have a materialistic worldview, but if one can grasp this concept it would make life make sense.

You are in a simulation, it’s an illusion, “All the world’s a stage.” -Shakespeare, “Life is just a series of events that never happened.” -Bobby Hemmit. People have been saying that life is an illusion for thousands of years. It’s Maya.

knock…knock… wake up Neo.

If Earth does break up into pieces then it wouldn’t be that big of a deal, it’s just data, it can be reset. But let’s say it wasn’t reset and Earth was no more. There are other worlds to incarnate into just in our dimension alone. Not to mention, you could incarnate into any period in Earth’s “history” or into both probable realities “past” and “future” (before the extinction level event or after it).

I think if someone has a materialistic worldview, they will have trouble with this concept and none of what I just wrote would make any sense lol. But thou shalt write anyway.
