If verses one and two were in the same day then God created a mess in verse one and started working on that mess in verse two. As the bible clearly shows in verse two, the earth was already there, only in a messed up state.
How do I know hell is in the center of the earth?
Isa 14:14 I will ascend above the heights of the clouds; I will be like the most High.
Isa 14:15 Yet thou shalt be brought down to hell, to the sides of the pit.
Luk 23:43 And Jesus said unto him, Verily I say unto thee, To day shalt thou be with me in paradise.
Mat 12:40 For as Jonas was three days and three nights in the whale's belly; so shall the Son of man be three days and three nights in the heart of the earth.
Luk 16:23 And in hell he lift up his eyes, being in torments, and seeth Abraham afar off, and Lazarus in his bosom.
Luk 16:26 And beside all this, between us and you there is a great gulf fixed: so that they which would pass from hence to you cannot; neither can they pass to us, that would come from thence.
Mat 27:52 And the graves were opened; and many bodies of the saints which slept arose,
Mat 27:53 And came out of the graves after his resurrection, and went into the holy city, and appeared unto many.
Isa 5:14 Therefore hell hath enlarged herself, and opened her mouth without measure: and their glory, and their multitude, and their pomp, and he that rejoiceth, shall descend into it.
First, the bible always mentions hell as being down, as in descending. That would put it somewhere in the earth.
Then Jesus said He would be with the thief in paradises.
And where did He also say He was going to be for three days and nights?
In the heart of the earth. Heart means, center.
So then, where was paradise?
In the center of the earth.
However, when Jesus told the story of the rich man and Lazarus, He said the rich man was in hell and also mentioned that there was a big gulf in between hell and where they were. Apparently, there were at least three large cavities in the earth.
So if paradise is in the center of the earth and hell somewhere down in the earth yet almost bordering paradise, I surmise hell is in the center of the earth.
After Jesus rose from the dead, and the dead ascended with Him. After the righteous left paradise, hell appears to have enlarged itself, possibly taking over where paradise.
