Uh, no, you are entirely wrong.
Not according to Buddha. There is ample evidence and proof He taught about God.
1. The Five Disappearances of His true Dhamma- His original Dhamma would be corrupted over time with man made ideas.
2. A counterfeit Dhamma would replace His Original one lost during the Five Disappearances (the counterfeit Dhamma is the one that denies there is a God)
3. A new Buddha would arise teaching the SAME truths Buddha originally taught.
4. Buddha said that His Dispensation would last 5,000 years but because women entered monastic life that it would only last half that time which is 2,500 years.
He even mentioned the name of the future Buddha as AmitAbha a derivative of Baha which refers to Baha'u'llah. Baha'u'llah means Glory of God. Buddha spoke of the great King of Glory as also in the Bible.
Baha'u'llah taught the oneness of God. Baha'u'llah, the return of Buddha did teach as prophesied what the original Buddha taught that there is a God but that teaching was gradually lost over time.
All these things are in the Buddhist scriptures. So the future Buddha would confirm what the original teachings of Buddha were which Buddha Himself said would be lost and replaced with a counterfeit Dhamma. Then the only way of knowing what Buddha actually taught is from the future Buddha which we say has come and is Baha'u'llah.
