Creation

The book of Romans explains so much about creation and the nature of man and reality as we know it. The Spirit quickly has Paul record this fact about the beginning:

For since the creation of the world his invisible attributes, his eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse. (Romans 1:20)

From the very beginning of time (the instant time was created), t=0, God revealed himself and continued doing so throughout history. He had an intimate relationship with Adam and Eve until sin entered the world; then because of sin, the relationship was broken, and God did not talk to men as he did at the beginning. But in the very Creation itself, he made himself known.

Therefore, just as through one man sin entered into the world, and death through sin, and so death spread to all men, because all sinned—for until the law sin was in the world, but sin is not imputed when there is no law. (Romans 5:12–13)

It was not long after creation that the fall occurred. We know that it was less then 130 years, probably much less because Seth was born when Adam was 130 years old and Cain had already killed his brother Abel before Seth was born. The fall and eventual curse changed the created universe in ways we do not even fully know. What was perfect was now corrupted. We cannot even imagine perfection, having been born in corruption.
