One thing that has been on my mind lately is "When did time exist?" As humans, we couldn't measure it until the sundial was invented, but time of course has existed. But since when?
I will look at this briefly from two perspectives. The biblical and scientific. Firstly, the biblical.
God created everything, so he must have created time. But for God to create time requires time. Even if it is the smallest of fractions of time, it still took time. So time must have existed before God created time. So did time exist before God? Looks like it has. So when before God did time exist?
The scientific view would start with the Big Bang. The Big Bang created the universe and such. But it took a very minute fraction of time to create the Big Bang, so therefore, time must have existed before the Big Bang happened and not during the process of the Big Bang, because it took time for it to occur. So when before the Big Bang did time exist?
I don't know how to answer these questions. If you are able to provide any philosophical insights or point out to me the flaws, please do so and I will attempt to refine them.
