In response to the question, "why did God create us?" the most straightforward response is "for His pleasure." In Revelation 4:11, it says, "You are worthy, our Lord and God, to receive glory, honour, and power, for you created all things, and it was by your will that they were created and have their being." This implies that God is deserving of glory, honour, and power. This is emphasised once more in Colossians 1:16, which states, "All things were created by him and for him." Despite the fact that God created humanity for His own pleasure, this does not mean that God was intended to be entertained or amused by humanity. God is a being of creativity, and the act of creation itself brings Him great joy. Because God is a personal Being, it brings Him pleasure to have other beings with whom He can have genuine relationships. God finds pleasure in having other beings.
Humans have the capacity to know God, and as a result, they are able to love Him, worship Him, serve Him, and have fellowship with Him (Genesis 1:27). This is because humans were created in the image and likeness of God (Genesis 1:27). God did not create human beings because He required them in order to fulfil His purposes. Because He is God, He has no requirements. He had never experienced feelings of isolation in all of eternity, and as a result, He never sought out a "friend." He has feelings for us, but that is not the same thing as being dependent on us. If we had never been created, God would still be the same eternal being that he is today (Malachi 3:6). There was never a time when the I AM (Exodus 3:14) felt discontent with His own eternal existence. Because God is perfect in every way, His action in creating the universe was also perfect. He did what pleased Him most when He made the universe. "It turned out to be excellent" (Genesis 1:31).
In addition, God did not create beings that are comparable to himself or "peers." It would be contrary to logic for him to do so. If God were to bring into existence another being with the same level of power, intelligence, and perfection as himself, then He would no longer be the one and only true God for the straightforward reason that there would then be two gods, which is obviously something that cannot happen. "The LORD is God; there is no other besides him," says the Bible (Deuteronomy 4:35). Anything that God creates must, by definition, be on a lower level than God himself. It is impossible for the thing that was made to be greater than or on par with the One who made it.
We are astounded, given that we are aware of God's absolute power and holiness, that He would choose to take man and crown him "with glory and honour" (Psalm 8:5) and that He would be so low as to call us "friends" (John 15:14-15). Why did God decide to make humans? God chose to create us not only for His own enjoyment, but also so that we, as His creations, would have the joy of getting to know Him.
