Enoch (Genesis 5) and Elijah (in 2 Kings 2) were both taken away by God and did not die. Whether they went to "heaven" or not, they did go to God.
Since Jesus is fully God, and is outside time with God, then even before he was born a man and died on the cross for our sins, he was the way, the truth, and the life. Why should God be limited by time, part of his creation?
