As Peter says in IIPeter 3, there were/are three different heaven/earth ages. We in flesh bodies are passing through the 'second' heaven/earth age. Genesis 1:1 In the beginning God created the heavens and the earth. That is a declaration and nowhere in the whole of the Bible are we told when this took place.
Genesis 1:2 AND ..... describes a catastrophic upheaval, Paul calls it the 'the foundation' which is actually a verb that means the 'casting down - overthrow', wherein some were predestined to do/be because of their 'perfect' love in Christ.
No one in flesh walking this earth can with for a certainty date this earth. But all the evidence demonstrates this earth is very very old.
This is a concept that I have broached on a few of the crevo threads. I'm usually told that the only reason scientists advocate for an old Earth is that their commitment to godless evolution requires the aeons needed for evolution to work. So that once I accept that there is a Creator, my belief in an old Earth can be discarded like a no longer needed crutch.
Fortunately for me and every other soul we have the perfect Judge and only He knows the 'intent' of any one heart/mind. The age of the heavens and earth are in my opinion a total side issue as to how long ago 'flesh human' bodies were formed. I cannot quite comprehend the miracle of how all the many peoples we can readily see are different could come from only two people. That speaks of evolution in really quick time.
It is my opinion that evolutionists know they are factually correct on an old earth and some know they are anti-god in claiming we flesh humans were spawned out of a primordial steaming pot of pond scum. Some of the intellectuals know this is a lie.

Out of curiosity, if you could have met Adam the day after he was created, how old would you have guessed he was?
