What is God Like

What is God like? What does it mean to fully want to have a deeper relationship with him. My thoughts are all mixed up and confused about that. God is so many wonderful descriptions but how is he different than a man on earth? Besides that he's perfect in every way and knows our thoughts before we've even thought it. What purpose did he create us? Did he just create us because even though he had angels he wanted some companionship? So many questions to what God is like and even more on having a relationship with him. I'm so eager to speak to someone about it but will it make more sense?
