What if every single person on Earth is a clone of the same person, and all our memories are implanted?

So what if the real person named Earth died long ago, and all the humans on this planet are genetically modified clones of him that have their memories programmed into their minds? This way, we all think we are different people with different pasts, life experiences, etc. What if every single human on earth is actually the same guy, and all our brains have just been programmed with different memories so we think we’re different?<br>What if the real Earth is just a really old man who has been dead for a long time, and all the humans on Earth are just his clones that have been designed to be able to do different things that he wanted to do and could not do in his life?<br>What if this planet is basically just a huge simulation designed to make these clones think they’re living a normal life, but really they’re just living out the life that Earth wanted to live but couldn’t because he died?
