It seems to me that the millions of events that happened in order to get to where we are now (alive on a rocky, water and oxygen-filled planet, in the Goldilocks zone of a healthy star) were sequential in nature and they took a finite amount of time to occur.

Assuming that there was A Beginning, where everything started at the same time, wouldn’t the steps to get to where we are in this process take about the same time for everyone else? Meaning that if there are other civilizations out there, that they’d more or less be as advanced as we are? Which is pretty sophisticated in certain areas at home, but not yet super capable in the long-distance human space travel department.

Not a scientist, just thinking out loud the thought I had reading the article.
