How did the first person come on earth?
The skeletons of these very early people have been found by archaeologists in places like Morocco in North Africa, Ethiopia and Kenya in East Africa, and in South Africa. So, one answer to your question is to say that the first person came from Africa around 200,000 years ago.

How many humans are on the planet?
7,800,000,000 peopleIn demographics, the world population is the total number of humans currently living, and was estimated to have reached 7,800,000,000 people as of March 2020. It took over 2 million years of human prehistory and history for the world’s population to reach 1 billion, and only 200 years more to reach 7 billion.
How was first human born?
The first human ancestors appeared between five million and seven million years ago, probably when some apelike creatures in Africa began to walk habitually on two legs. They were flaking crude stone tools by 2.5 million years ago. Then some of them spread from Africa into Asia and Europe after two million years ago.

What is the most populous creature on earth?
krillAmong all animals, ants outweigh us in biomass — putting billions and billions of tons up against humans’ fewer than 500 million. And while they’re both tiny and lacking a backbone, krill are the champs among animals worldwide, in terms of numbers, with a population estimated at 500 trillion.
What are living beings?
