We can only draw conclusions based on the evidence and the body of knowledge that we have. The time scales are not important as everything that we see ocurrs in the past, and I mean everything since the speed of light has a limit, even the events that happen in front of our eyes took place a few nano seconds before we perceive them.
That is why science is the best tool to acquire knowledge, it gives us a way of constantly improving our understanding as long as we remind ourselves that new discoveries might change how we view the world and we don't cling to outdated ideas.
