No. As af_vet explained, before the Incarnation, God appeared as visions or other manifestations (the burning bush for example) and/or His Word was delivered by messengers (Angels) who could be seen, but all of these phenomena were not Jesus, the Son of God, fully man and fully God.
John 1:18 "No man hath seen God [the Father] at any time; the only begotten Son, which is in the bosom of the Father, He hath declared Him."John 6:46 "Not that any man hath seen the Father, save He [Jesus] which is of God, He [Jesus] hath seen the Father."
Genesis 3:8-9 "And they heard the voice of the Lord God walking in the garden in the cool of the day: and Adam and his wife hid themselves from the presence of the Lord God amongst the trees of the garden. And the Lord God called unto Adam, and said unto him, Where art thou?
Since I believe the Word of God, and believe Christ is not a liar, and because He said "no man has seen God the Father, except Himself," and the Word of God states says the "Lord GOD walked in the Garden," the most logical conclusion to reach from the plain meaning of the text is that He who appeared and walked in the Garden was the pre-incarnate Christ, not an angel (as angels cannot be called the Lord God), was not the Spirit, as the Holy Spirit has a Name and He is not called the Lord God, and the text does not state that the Lord God appeared as a 'wind' by which the Holy Spirit may be like (see John 3:8; "The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit") and not someone or something that someone else claims who the Lord God may be which contradicts the Scripture.
