how often has the world renewed it self and how did humanity begin again

The idea that the world has “renewed itself” several times is usually a mix of science and myth. In science, Earth has gone through five major mass extinctions , but life never fully restarted from zero; it survived in smaller pockets and then diversified again.

How many “resets”?

Earth has experienced repeated global crises, but not complete erasures of life. The best-known pattern is the Big Five mass extinctions, where large numbers of species disappeared and ecosystems changed dramatically.

How humanity began again

Humanity did not “begin again” after a total wipeout in the scientific view. Modern humans, Homo sapiens , evolved gradually from earlier hominins over a long span of time, and our species spread, mixed, adapted, and rebuilt societies after disasters, migrations, and climate shifts.

Why people talk about a restart

A lot of “world reset” stories come from religious traditions, folklore, and speculative videos rather than settled science. For example, some religious accounts describe a flood and a new human beginning through Noah’s family, while other popular theories imagine repeated civilizations rising and falling.

Simple answer

If you mean scientifically , the world has not fully renewed itself in a clean restart; it has gone through repeated catastrophes and recoveries. If you mean mythologically , many cultures tell stories of humanity beginning again after a great disaster.

TL;DR

Earth has had several major biological resets, but life continued through them rather than starting over from nothing. Humans did not reappear all at once after a reset; we evolved over time and rebuilt civilization many times after local or regional collapses.
