What is the first creature on earth? - Steep oxygen decline halted first land colonization by Earth's sea - hzrn.com

You'll have to be more precise. Do you mean first life on earth, first microbe, first animal, first thing that crawled on the ground as opposed to swimming in the oceans?

All species originated from the sea so I'm guessing it was a fish.
However I'm sure the consensus would be a dinosaur. Hope that helps!

The first creature would be germs.

By the Bible it's man.(LOL)
Others say unicellular organisms were first.

Single Cell life forms, ha some might say humans - Adam and Eve - but that I dont think is true, sorry all Christians

I bet cells (and/or bacteria if that counts) were the first creatures on earth.

i think bacteria.nobody knows that clearly

noone can know actually what was it.. is it large or microscopic? noone knows..
if you know then tell me what was its food?

something possibly from the sea

It's hard to know because we people don't exist in that time so it's very interesting to know about the past lives of the organisms.. Like some Galapagos turtles like Harriet, George and well, I sure do believe that it is cells... :)
