Stromatolites are one of the earliest known life forms; some fossils may date back 3.5 billion years - before Earth had any oxygen in it's atmosphere.
The earliest ones still around are stromatolites, but there were lots of earlier life forms.
Yes. Our DNA has been passed on and changed/modified since the earliest forms of life.

The earliest forms of life were microscopic autotrophs that lived in the great prehistoric oceans. Living under the water protected them from the deadly UV rays from the sun, as at this point Earth had not developed a suitable atmosphere. This is true everywhere but Kansas, where the earliest life forms were Adam and Eve. Zing!

The earliest life forms on Earth were single-celled microorganisms like bacteria and archaea. These simple organisms emerged around 3.5 to 4 billion years ago in the ancient oceans of the planet. They played a crucial role in shaping the environment and paving the way for more complex life forms to evolve.
Yes
The earliest life forms were likely simple single-celled organisms, similar to modern archaea or bacteria. These early life forms would have lacked complex structures and organelles found in modern-day eukaryotic cells.
