You asked a very good question! I know that English teachers and grammar books say English verb tenses are about time, about “when” something happens, but in reality that’s only close to true.
In English the real difference between the “present simple” and the “past simple” is not about “time”, which is why your examples are both “correct”, they both are happening “now”, but they don’t have the same social impact. If you can “hear” which example sounds stronger or more “forward” and which one is weaker or more in the “background”, than you are on the right path.
Unfortunately it would take a whole book to fully show how the English verb tense system really works….and you can find an electronic version of that book here.
I hope that helps.
