What was there before us?

There are many questions that I am hoping I will get the answers to once I get to heaven. After all, I will have eternity to wait my turn and ask God my petty ponderings. But the one that has been plagueing my mind lately is this: since God existed in eternity past.....what existed before all that He recorded for us in Genesis 1? Are we the only creation He ever made that He loved so much to send Jesus to suffer our pathetic means of torture for? Are we humans the only ones He ever gave free will too? Well I can at least answer that last question, no, the angels obviously have free will because Lucifer and others CHOSE to rebel against their Creator while the rest CHOSE to remain faithful to HIM. Are we the first of human-reflection of God Himself-kind?
Are we the first ones to have a love letter/Basic Instructions Before Leaving Earth book (BIBLE) from God? Would we have been made aware of the answers to these questions and SO much more had sin not entered our lives?

Your thoughts????
