I agree with this. If Dinosaurs roamed the earth over 65 million years ago. And the earth is predicted to be swallowed up by the sun's red giant transformation in about 5 billion years. We have more than enough time.
Could it be that people are so short sighted when it comes to comprehending the extent of how long that is? 5 Billion, our recorded history is a mere few thousand years old. Thousands vs Billions..To say never is just ignorant.
