Yes, I believe God created everything. It was also the same God that became a little human baby, destined to die for mankind. He wasn't given the name Jesus until He was a child. So, before He came to earth and lived a life as Jesus, He created the earth and weed. At the time He created everything, He had not been born a man or recieved the name Jesus.
I believe that when I die, God will give me a new name. Even though I don't know what it is, it is still 'my name'. The same as Him. He wasn't named Jesus, yet, but He was destined to recieve that name. So, Jesus created everything before He bacame a man or recieved the name Jesus.
Now He has already come to earth and left. The only way a man can know God is by knowing Jesus. By becoming man, we are better able to understand God's personality. A man just isn't able to comprehend God unless He stoops down to man's level. Man met God face to face, and wrote about it so we would know what God was like. Because I am human, it helps me to look at God through Jesus so I can understand His personality, a little better.
