Time (some questions)

Time is an interesting concept. What is time? Why do we value it so much? What would it be like if time didn't exist? Indeed, would it be possible for time to not exist? What was it like in the "time" before the Big Bang or what was it like in the "time" before God created the universe. Indeed, if there is a God who created the Universe what "time" did he come into being? Can something exist in all time? Think about it. How long has time existed? Will there be a time when time ceases to exist? If we aren't around will it matter? Some things to mull over while you are enjoying your lunch.
