Fossils can form even if microbes are not present. Microbial fossils, such as stromatolites, can form when microbes are present and leave behind structures or chemical signatures that are preserved in the rock record. Non-microbial fossils can include the preserved remains of plants, animals, or other organisms from ancient environments.
Fossils are unlikely to be found in igneous rock because igneous rock forms through the cooling and solidification of molten rock, which destroys any fossils that may have been present. Most fossils are found in sedimentary rock layers where the remains of plants and animals can be preserved over time.
A scientist who digs for fossils is called a paleontologist. They study ancient life forms and the history of life on Earth by examining fossils found in rocks.
No, not all microbes are unicellular. While many microbes, such as bacteria and some algae and fungi, are unicellular, there are also multicellular microbes, like certain fungi (e.g., molds and mushrooms) and some algae that can form complex structures. Microbial life encompasses a diverse range of organisms, including both unicellular and multicellular forms.
It is so because, the oldest fossils are obtained from the life forms which used to exist at that time in the oldest ages. At that time there was no so much changes in the world, the life forms being simpler. As the age of the earth advanced hence the forms of life also adapted or tried to adapt to the changes of the surrounding. The climate changed and so did the life forms. It was determined that in the older times, 1st life forms came in the water bodies and then from there the land forms developed. So as we see the later life forms are more complicated, thus the oldest fossils are more simpler compared to their most recent counterparts.
Another kind of fossil is a mold or cast fossil, which forms when an organism's remains decay and leave an impression in the surrounding sediment that is later filled with minerals. Another type is a trace fossil, which is evidence of an organism's activity, like footprints or burrows, preserved in rock.
The fossils of the oldest life forms can be found in the Precambrian period of the fossil record.
There are 5 that can be resurrected from fossils if you include their evolution forms as well.

Fossils can be made of any material that deteriorates slower than the sediment that forms the fossil hardens
