of the 5 questions there, the first four are found in the Bible.
Here is something interesting. The US Oceanic Institute did not know until the around 1940's that there were fresh water rivers flowing in the oceans.
They could have found that out simply be reading the Bible and learned that was stated over several thousand years ago. That without BLOOD flowing through yer veins, you will not have LIFE anymore. The Life of the flesh is in the blood... Consciousness and life are easy. First three chapters of Genesis tells you everything.
God created time as well for mankind. He is not bound nor restricted by time. He is always present at whatever point in time.
We need not worry about the "future" because GOD is already there waiting for us to arrive. Just one of HIS attributes that surpasses man's understanding . He is everywhere present at ALL times.... Omnipresence and ominiscience..
SHame the so called "smart" people don't spend any time reading a BOOK writtena nd preserved by the Creator of the universe and everything that exists, including all living life or they might actually learn a few things...
