false because scientist make a hypothesis, and some of them are not even correct, so they probably would round that year to another year. For example; I found this fossil and it looks like it is 1,000 <<<< this cannot even be true but it can be an inference or a hypothesis. Also, I must first figure out when it was born, and all these other stuff. So that's why scientists are not able to determine the relative age of rocks. I hope this helps!:) :D And please give this a THANKS :) :D and the BRAINIEST ANSWER/CROWN! :) :D
