I feel slightly amused at your certainties based on dreams and visions. All actual observations show that events are always preceded by earlier events and succeeded by later events, and thus all time points are preceded by a past time point and succeeded by a future time point. Thus the default theory is all time points have a past and a future and hence time and the physical reality is eternal. It is you, who is going against all observable evidence in support of this and saying that there was once a time point preceded by no previous time point! Since you are going against observations, the onus is on you to marshall evidence for such an extreme deviation from observations made so far by humans. Dreams are not going to cut it.Science may have well thought out theories, but evidence is require. Where is the evidence, not the math, for eternity in the universe? I admit to a bias, I know for certain God exists. Knowing God is the only eternal being in existence, it is easy for me to say, where is the evidence? Even if you saw God, no one would believe you. They would require empirical evidence. I know the argument, given time science will have the answer. What if, however, there is no scientific answer? How can you prove God?
Assuming God created the universe, there would be no scientific explanation. Until the end of time science will spin it's wheels to no avail, there is no way science can explain it. In the meantime, it is amusing to watch science attempt an explanation. It's better than a science fiction movie.
Meanwhile evidence continues to mount that the universe is infinite in space.
