Was the earth as it is today when it was originated? Explain​

see below

Explanation:

Back in the day I feel as though it was a cleaner place because we did not have all these machines polluting the air and a bunch of other horrible things for the earth but now we have machines putting chemicals into the air therefore making everything different making it hard to breathe for some places. Therefore the difference between what the world was first and what it is now is that the earth is polluted and the population of a lot of animals is going down Thus being really different today in Society.

No. It was not. It is believed that, Earth was formed nearly 4.5 billions years ago.

Explanation:

According to NASA Science, when the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.
