Was God alone in darkness and silence doing nothing whatsoever and bored to death before he created the Universe?

Answer 1

This question is actually based on a philosophical misunderstanding. To be "God" presupposes that the Existence in question is uncreated. God therefore is outside of time and space, which are creatures. Since God is omnipresent and the source of all creation, all of time is always present to Him. This means that God sees everything simultaneously, like a moment, whereas we, who are subject to time and space, experience these things in a linear fashion. As a result, there was no "before" or "after" to God - God only sees things as now.

Answer 2

If we take literally the biblical concept of creation, then we probably should take literally the entire biblical narrative about creation. There are actually two creation accounts in Genesis: (1) verses 1:1 to 2:4a; (2) 2:4b to 2:22.
In the first of these, the ocean was already present and a wind moved across the surface. The seas rested on the dry land, which appeared on day 3 when God gathered the waters together. The first thing that God had to do was create day and night. So, although God was not entirely alone, this account certainly says that he was in darkness.
In the second account, there was pre-existing dry land, but God had yet to make it rain for plants to grow. A spring arose and God's first act of creation was to take some moist clay and made Adam. It appears from this account that all the basics were there - the sun and moon and stars, as well as the earth itself, but no living things. So, God was not entirely alone, and certainly not in darkness.
It may seem surprising that, in both creation stories, the basics were already there - the waters, the dry land, the wind and therefore the air. Many experts in Hebrew have carefully examined the texts and confirm that this is what they say. The biblical creations were not ex nihilo. Yair Zakovitch, Dean of Humanities at Hebrew University is quoted as saying, "The thing to remember about the Bible is that the events and characters are just vehicles to convey messages. The biblical narrative was written to educate our young nation, not so much to tell us what really happened."
