do you believe "reality", as it is known to man, remains the same throughout time?
I'm not sure I understand the question.
Evolution is based on a study of objective evidence. It doesn't depend on opinions or preferences.
Every living thing descended from a common ancestor. There is no other possible way to explain the abundance of evidence from multiple independent fields of study.
It is also open to falsification. One rabbit fossil in a preCambrian rock strata would blow it to smithereens. So far so good.
