Sponge.

Answer 1

The first life on Earth was most likely unicellular organisms. These early life forms were simple, single-celled organisms such as bacteria and archaea. They emerged around 3.5 to 4 billion years ago and are considered the ancestors of all life on our planet. Animals and sponges, which are multicellular organisms, evolved much later in the history of life on Earth.
