Marks of beast or God are hypothetical ...no "mark" exists as it is your soul that God is concerned with...humans took old writings and wrote books to invoke fear...not because God is a judgmental pr**k, but because a few humans discovered they could make millions off the idea of God...sadly they who love money don't know the true God...one day God will return...and all the people who claim they are they way...hmmm..I have a feeling they might find a fork road in the afterlife...
........Okay, If you says that there is no marks,then you don't know your Bible good. Read Revelation 14:6-12. The third angle message. Second,nobody has their own soul or spirit who live in their body. There are two kind of spirit who can enter human body. That is the demons or the Holy Spirit.
