Precambrian rocks are very old and have experienced the most erosion, There is very little fossil evidence in rocks believed to be Precambrian .

Explanation:

Specific events are often deduced from fossil evidence. As there is very little fossil evidence found in Precambrian strata, there is little that can be deduced about specific events.

Precambrian strata are believed to be the oldest geological strata.
The oldest strata would have experience the most erosion and geological changes. Erosion and geological changes such as plate tectonics and volcanic activity destroy the evidence that might be found in the geological strata.
