What is the biblical basis for the logos in John 1:1-3 not being Jesus (yet)?

> 1In the beginning was the word, and the word was with God, and the word was God. 2he was in the beginning with God. 3All things came into being through him, and without him not even one thing came into being that has come into being. John 1:1-3 BLB We are told in v14 that 'the logos became flesh'. This refers to Jesus and his subsequent conception and birth through Mary. This question seeks to determine if it can be shown biblically that the logos referred to in John 1:1-3 is *not yet*, Jesus. IOW, Jesus, born through Mary and the HS, is *not* being referred to in John 1:1-3.
