We should be digging up cities full of evidence of other intelligently evolved life forms. Or are we the only ones who have evolved to our level. Show us remnants of a city of the Lizard King. Or the underwater markings of the Dolphin King.
Was there only enough time for us to evolve and no other life forms.
Gen 1:26-27
26Then God said, Let us make man in our image, in our likeness, and let them rule over the fish of the sea and the birds of the air, over the livestock, over all the earth, and over all the creatures that move along the ground.
You will find evidence for the scripture listed above just by looking at the truth of reality. No animals rule over the fish, as well as the birds, as well as every living creature that moves on the ground.
Why? Because the Creator became a Man and lived among us. Jesus Christ is creating a better place for us presently. Why do we believe this? Because everything else he told us and showed us is true. It's that simple.
