Many people imagine that the term God comes from the term Zeus, a Greek deity. This is because the person who defines it, has not studied the etymology of words. Etymology, is the study of the origin of the word.
In this case, the word god is defined to have arisen in ancient Europe, being called Proto-Indo-European, that is, the ancient language of that region. In that ancient time, everything that came from heaven was called "dyew". So everything that came from heaven was described by this radical. To define an entity from heaven, "deywós" was used, with time the ancient population of the region of Italy used the term as "deiwos", and later changing to the term "god".
We have for example that the term Zeus is Greek. But the word god does not come from Zeus, because the term Zeus is created long after the term "deywós", so it is impossible for the term "god" to have arisen from the term "Zeus". But what happened was the opposite. The term Zeus, used the radical "dyew", to define it as an entity from heaven. But the term "god" does not come from the term Zeus, the term "god" comes from the same meaning from heaven.
It is clearly observed that the term God has no passage in Greece, in which the term Zeus was created. So it is impossible, that the term "god", came from the term "Zeus".
So saying God to the higher entity in the Bible does not tend to be wrong, as we define that God is in heaven.
So etymologically speaking every time God is spoken, he is talking about an entity that is from heaven.
The Hebrew term "el", which translates, like God, means "powerful", so to call the celestial entity, powerful, or to call it celestial. Logically, there won't be much difference. What we should always have is a more discerning, logical and pacifying concept, to analyze things. Many problems occur due to ignorance, partisanship and a combat factor. So defining God as the entity in heaven is not a bad thing. In fact the important thing is not what it is called, but the respect and obedience that one has.
