I am not sure about that (time travel lol), but I do have a theory or rather wild guess. The history is repeating itself on this planet over and over. When we become advance enough to produce weapon of mass destruction, our nature (greed, hunger for more power and more wealth, also suspicious of others) will eventually get us to destroy each other. When that happens, we start all over again.
From another article I have seen over a decade ago, it concluded from the study of DNA of people from all over the world that - every last one of the 6 billion (back then) people on the earth are of the descendents of no more than a group of 2,000 "survivors" based on the DNA difference.
Something must have happened before. It could be a natural disaster on a planet scale, or it could be an all out world war involved weapon of mass destruction. I do believe there could be a lot more people survived the initial disaster whether or not it's man made or natural, but think about it. After the economy and productivity being disrupted or rather completely destroyed, most of the initial survivors will starve to death, because we are not taught to survive without the society we are in now. Even farmers might find it hard to sustain themselves without be able to buy all the supplies for their farms. Then after a while, there could be just thousands survivors left who will spend all their time and effort on surviving. Who got the time to teach kids about math, science, history, etc. when they still have trouble to feed themselves? After some generations, all is forgotten, and nobody knew there was greater civilization before them.
Earth population might take hundreds of thousands of years to recover from such disaster. Eventually humans will reach the same technology level (might be different technologies, but same level) as before the last disaster took place, then it might happen again.
Who knows. Just a wild guess.
Don't take my word on it, I am not sure either haha
