I would be more worried talking about the Lord of Lords as you just have! You words are intended to be outragous and are an offense to God!
Mary was acknowledging something you seem not to understand,the Sovereignity of God.God had selected her.He didnt ask for her "permission" ,the word is submission..she submitted to the will and plan of God. She was overcome by His grace,"no" was never an option for her..any more than it is for any man or woman that has been drawn by the grace of God.
He knew what her answer would be.
As for Mary being the "co creator"...go ask Jesus what that means
Matthew 12
47 Someone said to Him, ""Behold, Your mother and Your brothers are standing outside seeking to speak to You.''
48 But Jesus answered the one who was telling Him and said, ""Who is My mother and who are My brothers?''
49 And stretching out His hand toward His disciples, He said, ""Behold My mother and My brothers!
Those who hear and obey are His mother and brothers and sisters..
