Is God a person, phenomenon or material?
If we assume God to be a person, then starts the difficulty of answering questions like -what gender? What race? What color? And most difficult -who are his or her parents? Our experience tells us that every born person will have to have biological parents so most natural thing for us would be to assume that God has parents. For example God Ganesha's father is Shiva, Lord Krishna's father was Vasudeve and likewise for other Gods. However once we make this assumption that God has parents then next challenge comes up- is the God who is having parents really a supreme God? or his parents are the real Gods? We can never answer this question because every parent will also have parent. But still if we continue to believe that God is a person then we also have to accept the fact that as he has parents and probably brothers sisters as well so he might not be absolute God but may be creator of some planets or may be some regions on earth planet. This would also mean that different regions on earth might be reined by different Gods how might be from same family or cousins or even enemies.
If we assume God to be a matter then things become little easier and also fit with general characteristics of God defined in more or less all cultures. As matter need not have parents but only ingredients so if our God is matter then it can be universal God. But if God is matter then it can be recreated or copies can be made, but that is not a problem as any way humans do not know yet how to produce God. However if we assume God to be matter than there are some questions to be answered like how this matter helps organizing or benefiting the world. One possibility could be that God is a mass of energy and humans and possibly animals also draws emery from this mass and gives it back when they die. Ok, so far so good. Now the big teaser.. How this matter created humans? Possibly humans grow on this mass of energy like fungus grows on wood. But this would also mean that God in form of Wood would be catalysts but not the creator. So There must be something else which created first life.
Can God be neither a person or matter but a phenomena or may be just an event or an illusion? Can this whole world be an illusion? Neither matter nor persons. When waves travel on the surface of water they have energy and mass, troughs and dips but technically sum is zero that is they are just disturbance on the surface. Can it be possible that this whole world including God is just a disturbance having positive and negative energy sum of which is zero? Every mass can be actually only energy e=mc2. Thus every cell or particle in our body is not actually matter but just packet of energy. We all are just vibrations some part in positive and some part in negative but sum is zero. Our thoughts, pain and joy we feel are also just vibrations having positive and negative energy in our mind?
Possibly we will never know what or who God is so it is our choice and individuals to understand God in our own ways.
