Evolution means change over a period of time. The fact that Earth is roughly 4.5 billion years old has shown us those changes in fossil records, geography, human evolution and carbon dating. So we see Evolution happening over that time and that's what makes it not a theory but fact.
In itself, it isn't - at least, not directly. The age of the Earth does place constraints on the amount of time in which the current diversity of life could have evolved from its earliest precursors, but that's about the extent of its relevancy. And given the fact that we now know the Earth to be about 4.55 bln years old, and that we know life to have existed for at least 3 bln of those years, one may safely consider it a moot issue.
Knowing the age of the rock the fossil was found in is important because the age of the rock and the age of the fossil are usually about the same.
Because evolution takes a long time and if the earth is not millions of years old then the theory of evolution is a lie
the changes that matter undergoes are the physical and chemical change by:R.yu
This is called reaction rate.
Evolutionary change is a process where things change over a period of time. Such as going from a candle, to a light bulb.

That is correct, a candle (or the material of which it is composed, which is usually paraffin) undergoes a chemical change when it burns.

A very important mechanism of evolutionary change besides natural selection is geneticc drift.
The chemical composition of a substance does not change when it undergoes a physical change.

chemical change.
A substance that undergoes change in a chemical reaction is called a reactant.
This phenomenon is known as coevolution, where changes in one species can drive changes in another species as they interact and exert selective pressures on each other over time.
It does change its physical look but it does not change chemically.
