Both the time and season belongs to God, we study those things that are already in existence to bring out our new discoveries, their is nothing new under the heaven. Though, we can build on old things to suit our present need, but the new discoveries are not so new, they still depend on the old.

These are the kind of questions we should leave for God to answer.. Smile
Because we will all come from different angles of viewing things, and non of us might be correct at the end of the day.
