In statistics, why do you reject the null hypothesis when the p-value is less than the alpha value (the level of significance)

This is a question that I've always wondered in statistics, but never had the guts to ask the professor. The professor would say that if the p-value is less than or equal to the level of significance (denoted by alpha) we reject the null hypothesis because the test statistic falls in the rejection region. When I first learned this, I did not understand why were comparing the p values to the alpha values. After all, the alpha values were brought in arbitrarily. What is the reason for comparing them to the alpha values and where do the alpha values of 0.05 and 0.10 come from? Why does the statement ${p}_{\text{value}}\le \alpha $ allow you to reject ${H}_{0}$?
