“Is there ANY Scriptural evidence that points to anyone other than GOD and His Angels in Heaven interacting with humans on Earth?”
Yes, many. The problem arises when our ego plays God and thinks that it is the Holy Spirit. The Holy Spirit teaches through epiphanies. There are many scriptures reflecting communication with the Holy Spirit.
There are good reasons that the gifts of the Holy Spirit are the opposite of many of the attributes reflected on this thread.
