I'm not really wondering what caused God. Its more so there's two possible. God created the universe or the big bang.
God essentially was the big bang when it comes to what happened to the earth.
The earth is millions, if not billions of years old, and the bible does not dispute this. In fact that Bible states that the scoffers in the last days are "willingly ignorant" that the heavens are of "old" (diiferent Greek word than most of the other Greek words utilized for old) and the earth was standing in and out of the water. When was it covered in water? Already in verse two of Genesis -before the 6 day creation period of this age.
Genesis 1:1 "In the beginning God created the heaven and the earth."
Genesis 1:2 "And the earth was without form, and void; and darkness was upon the face of the deep." -
The word void is bohuw -
void
922
bohuw (bo'-hoo); f
rom an unused root (meaning to be empty); a vacuity, i.e. (superficially) an undistinguishable ruin:
KJV - emptiness, void.
But he tells us in Isaiah, he did not create it that way. He created it to be inhabited. So we know then he did not created a mass covered in water (in a ruined state) So that also tells us it became that way. So we know that the word "was" should be translated "became"
was
1961 hayah
hayah (haw-yaw); a primitive root [compare OT:1933]; to exist, i.e.
be or become, come to pass (always emphatic, and not a mere copula or auxiliary):KJV - beacon, altogether, be (-come), accomplished, committed, like), break, cause, come (to pass), do, faint, fall, follow, happen, have, last, pertain, quit (oneself-), require, use.
The bible is not a complete history or science book but it does touch upon that time in Jeremiah 4-
He takes us back to Genesis 1:2
Jeremiah 4:23 "I beheld the earth, and, lo, it was without form, and void; and the heavens, and they had no light."-
Genesis 1:2 "And the earth was without form, and void; and darkness was upon the face of the deep."
Jeremiah 4:24 "I beheld the mountains, and, lo, they trembled, and all the hills moved lightly.
Notice all the hills moved lightly,? Everything shifted at that point. That's why in certain maps everything looks like it used to fit together. God literally shook the earth (and he will again in the future)
Jeremiah 4:25 "I beheld, and, lo, there was no man, and all the birds of the heavens were fled."
Jeremiah 4:26 "I beheld, and lo, the fruitful place was a wilderness, and all the cities thereof were broken down at the presence of the Lord, and by His fierce anger."
It was once a paradise and it will be again in the future.
Jeremiah 4:27 "For thus hath the LORD said, The whole land shall be desolate; yet will I not make a full end."
And he didn't. But we aren't talking about Noah here, remember in context, he took us to Genesis 1. And In Noah's time, there were men saved.
And once again, the word itself states that latter day scoffers are willingly ignorant about how old the heavens and earth are-
II Peter 3:4 "And saying, "Where is the promise of His coming? for since the father fell asleep, all thing continue as they were from the beginning of the creation."
II Peter 3:5 "For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water"
Point being what is thousands of years compared to how old the earth really is.
