yes.
Cells/Bacteria.
Earths first life form may be non photosynthetic bacteria.
The smallest life form discovered until today 2010 is an Archaea microbe, roughly 200 nanometers across (the size of a large virus, which is not considered to be alive because of its inability to reproduce independently) found in an abandoned mine in Northern California in 2006 by Brett Baker working with Professor Jill Banfield.
The simplest life forms known on Earth are typically single-celled organisms such as bacteria and archaea. These organisms consist of a single cell that performs all necessary functions for life, including metabolism and reproduction.
The 34000-year-old bacteria that's still alive
Bacteria are usually considered as one of the pioneering generations of life on earth by the scientists.

No. It is too hot, but life does exist in caves and there is a wide range of what can be found from the smallest bacteria to the largest bat.add. By and large, life forms require water and water below 100 deg C. And that rather limits the possibility of life forms in the interior of the Earth.

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.
