onenerdykidAccording to New Testament scripture, Jesus is not God in human form. He is the son of God. If it's someone's belief that Jesus is God in human form, then they can believe that all they want. All I can do is go off the written ideology. But there are some philosophical & theological problems with God being human, which Aquinas and Augustine go into good detail and why they as well come to the conclusion that Jesus was a mortal man. Very interesting, very detailed, and very long argument that I don't feel like hashing out here. But if you care to delve into it, they (especially Aquinas) are the ones to look into.
Your second argument is straight from the famous "Problem of Evil"- Since God is all-perfect, all-knowing, all-good, and all-perfect he would without question know what the perfect world would be, he would be able to make it, and it would be perfect. Since God made the world we have, the world we have is therefore perfect. Any change, even one less mosquito or one less child with terminal bone cancer, would be a less perfect world. If someone truly believes this and that the current world is perfect, then I don't think they actually understand just how good and how perfect it should be if an all-powerful, all-knowing, all-good, all perfect God were at the helm. Additionally, such a God wouldn't need to try or to experiment with life a few times in order to figure it out. He would by definition already know how to do it and be able to do it. There would literally be, as you noted, no mistakes.
Talking about "the problem of evil" will be a never ending loop.
The fall of man is what caused evil and pain in the world. God gave us free will, and that is what created pain and suffering. This is VERY different than God "allowing" or "creating" evil, pain, suffering, etc.
The entire point was that the mechanics of our world are incredibly precise and perfect. Not that all human interactions and lives are perfect. No one is making that argument--we know exactly where suffering came from.
As for Jesus not being God--where are you getting this from? Have you read the New Testament?
Here:
Isaiah 9:6 - For unto us a Child is born, Unto us a Son is given; And the government will be upon His shoulder. And His name will be called Wonderful, Counselor, Mighty God, Everlasting Father, Prince of Peace.
Matthew 1:23 - “Behold, the virgin shall be with child, and bear a Son, and they shall call His name Immanuel,” which is translated, “God with us.”
2 Peter 1:1 - "Simon Peter, a servant and apostle of Jesus Christ, To those who through the righteousness of our God and Savior Jesus Christ have received a faith as precious as ours:"
John 1:1-3 - In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through Him, and without Him nothing was made that was made... 1:14 - And the Word became flesh and dwelt among us,
John 8:58 - Then Jesus said to them, “Most assuredly, I say to you, before Abraham was, I AM.”
John 10:30-33 - Jesus answered them, “I and My Father are one.” Then the Jews took up stones again to stone Him. Jesus answered them, “Many good works I have shown you from My Father. For which of those works do you stone Me?” The Jews answered Him, saying, “For a good work we do not stone You, but for blasphemy, and because You, being a Man, make Yourself God.”
Mark 16:19 - "After the Lord Jesus had spoken to them, He was taken up into heaven and sat down at the right hand of God."
God is the Trinity--3 in one.. Father, Son, and Holy Spirit.. Before Abraham was I AM, Jesus said that. The Word was God, and the Word became flesh and dwelt among us.. That means that God dwelt among us, as Jesus.
