Jesus told us: ‘But from the beginning of the creation God made them male and female’ (Mark 10:6).
In these words of Jesus we find He teaches that Adam and Eve were created in ‘the beginning of the creation’—not billions of years after the beginning!
Jesus was a young-earth creationist. Jesus consistently treated the miracle accounts of the Old Testament as straightforward, truthful, historical accounts (e.g., creation of Adam, Noah and the Flood, Lot and his wife in Sodom, Moses and the manna, and Jonah in the fish). He continually affirmed the authority of Scripture over men’s ideas and traditions (Matthew 15:1–9). In Mark 10:6 we have the clearest (but not the only) statement showing that Jesus was a young-earth creationist. He teaches that Adam and Eve were made at the “beginning of creation,” not billions of years after the beginning, as would be the case if the universe were really billions of years old. So, if Jesus was a young-earth creationist, then how can His faithful followers have any other view?
If you liberal Christians reject a literal Genesis in favour of evolutionary ideas (or even just millions of years), this puts you on a slippery slide of unbelief. If we re-interpret God’s Word in Genesis to fit man’s fallible opinion, then ultimately, it would only be consistent to apply this same hermeneutic (method of interpretation) elsewhere — even to Christ’s Resurrection. Your and other liberal Christians need to get off that 'slippery slide' of unbelief.
Psalm 118:8 warns us:
"It is better to trust in God, than to trust in man."
