It is just as incorrect to assume the Bible is inspired as it is to assume that God exists, or to assume he or some personal being or “life” does not exist. If it’s an assumption, then it is not a decision reached after considering the best available reasons. This does not mean every belief with supporting good reasons is the right one, only that beliefs with good reasons supporting them are better than are those beliefs without good reasons, or beliefs which are based purely on one or more assumptions.
The period of our human life outside of our mother’s womb begins when we are born, and it ends when we die. The “time” of this period is the length of years, months, days, and however many other accepted life sequences can be measured. Again, as we use it, “time” is a discernable measurement of events, actions, or periods, or other similarly measurable things, that occur. Anything that is measurable in this way is “in time,” by being measured by time, at least in terms of how we actually view time and use time in our lives. Thus, “time” is as old as the first act, or as eternal as the acts, or even the thoughts (if sequential, as are our thoughts), of Jehovah God himself.
