here's why everyone on earth is actually your cousin this is your family tree and if you go back around five generations you can see that you'll have 128 great-great-great-great-great grandparents if you go back 40 generations math will tell you that you had over a trillion ancestors all alive at the same time which is clearly impossible so obviously there must have been a ton of inbreeding between your ancestors and that's only 40 generations when you consider the fact that humans have been around for about 7 500 generations that's a ton of ancestors and a ton of inbreeding that should technically mean you have two to the

7500 ancestors but that's just such a large number you just can't comprehend it and with a number that large probability says it's nearly certain that every single person on earth has had a shared ancestor which technically makes us all cousins
