The answer to this question can depend on your religion, if you are catholic, the answer to this question is grass, however, if you are another religion, then I'm not sure, and if you are an atheist, and believe firmly in evolution, then the answer is bacteria, or another micro organism.
Unicellular plants and animals were first forms of life on Earth
Earliest life form is microbe, a unicellular organism. First bacteria can dated back to 3.4 billion year ago. Emergance and true cut point from being a replicating molecules to a living cells is still unknown.
In my knowledge, the microorganisms lived first on earth.
Four events that had to happen before life could form on Earth include the formation of the Earth from cosmic dust and gas, the cooling of the Earth's surface to support liquid water, the development of an atmosphere with essential gases like oxygen, and the emergence of organic molecules through chemical reactions.
The first life on Earth were single-celled organisms such as bacteria that appeared around 3.5 billion years ago. These simple organisms evolved over time into more complex forms of life.
Unicellular plants and animals were first forms of life on Earth
Life is defined by the ability to metabolise, grow and most importantly to procreate or multiply. Supposedly, the first life on earth came in the form of coacervates.
Plants came first in the evolution of life on Earth, appearing before animals.
life first started from bacteria that is in a human body and it starded life on the earth and it is true.
it was either mars or earth i think it was mars
Earths first life form may be non photosynthetic bacteria.
Plants
Scientists believe that the molecule that came first in the evolution of life on Earth is RNA (ribonucleic acid).
Life is believed to have first appeared in Earth's oceans around 3.5 billion years ago. This was in the form of single-celled organisms like bacteria and archaea. These early life forms were the foundation for all subsequent life on Earth.
Scientists think that the first life forms appeared on Earth about 3.6 billion years ago. These were simple cells that eventually evolved into the abundance of life we see today.
eff the time in wich life first evolved on earth!!
It is likely that there is life in space - the first life on Earth had to come from somewhere and it's generally accepted that life first arrived on the back of an asteroid. But if there isn't any, it'll be down to lack of atmosphere and unsuitable temperatures.
