Evolution is real but there is some circumstance where evolution is not valid and to get to the bottom of this we need more than the scientists knowledge (because only the Person that creates the earth and the things that abide in it tell us the fact) because some aspect of their understanding about the earth and human creation can be misleading.
Back to the question, are humans superior forever? Yes, because they are created in God's image and also given the authority to dominate the earth. This is the reason why satan was jealous.
Okay, let us agree that God created the world, their are many organisms that have been existing before the creation of humans, is God planing to create other being more superior to man. Evolution can take millions of years. Let us get back to the same question Back to the question, are humans superior forever? Yes, because they are created in God's image and also given the authority to dominate the earth. This is the reason why satan was jealous.
Meanwhile, if another evolution will happen it will or maybe through human errors just like we see different diseases that come out of the blue.
