Was the Earth in flood-stage in Gen1:2 ? Did it "perish" after Noah's Flood?

Isa45:18 For thus saith the LORD that created the heavens; God himself that formed the earth and made it; he hath established it, he created it not in vain, he formed it to be inhabited: I am the LORD; and there is none else.

Jer4:23 I beheld the earth, and, lo, it was without form, and void; and the heavens, and they had no light. 4:24 I beheld the mountains, and, lo, they trembled, and all the hills moved lightly.
4:25 I beheld, and, lo, there was no man, and all the birds of the heavens were fled. [Any on the Ark?]

2Pet3:5 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:

3:6 Whereby the world that then was, being overflowed with water, PERISHED(!) [You think?]

3:7 But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.
