How can Jesus be God when he is born on Earth?

If Jesus is god, why was he born? Why does he have a mother? Why did a woman get pregnant with him? Why did he go through periods like babies, children, teenagers? He could have landed directly on earth as a human. Does anyone agree with me?

By the way sorry for my bad English, English is not my first language I hope you get my point 😅😅
