Why didn't the early geologic time scale include the number of years ago that events happened?

Paleontologists didn't have the technology in that time to get a good estimation on the events.  Back then, they had to rely on natural sources "markers" that made the estimations. Those estimations weren't accurate. Today's measures are accurate.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
