“Then God said, ‘Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.’ Thus God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament; and it was so.” Genesis 1:6-7.
You cannot prove that there is a God. Have you heard that one? Is it true? The only real opposition to God’s existence is the theory of evolution; that and willful unbelief.
