Let me back up and say i don't have any issue with science. The issue I have is that man always trying to take credit for God's stuff and not give credit where credit is due and then try to justify
SIN and slackness. The very laws that give science credibility came from God. It's called control and order. Without these two things there is no science. Yet some scientist will claim that this control and order came out of chaos. An assumption not proven to exist anywhere else in the universe. It's to hard to for science to believe that a God with purpose in mind set everything in motion. Science is good at telling you the 'how' but it always fails at telling you the 'why.' This is so because the 'why' or the purpose of all things are wrapped up in the heart of God. Purpose:The original intent for creating something. If you don't believe in God, that will always be hid from you, even the purpose of your own life. You'll be stuck in the how to live, but never know why you're alive.
Concerning Adam:
It's not so hard to understand how one pair can spawn many if you understand how God works. However, there is a premise. First, we must at least acknowledge that God is not just smarter than us. He is beyond us at levels that we can't track with our mental capacity. The proof is in the order and balance upon which creation holds together. The details and the intricacies more that suggest a wisdom beyond anything we can duplicate.
Upon that premise place this principle. God creates the end and then starts at the beginning. God created everything once and He created it fully ground, animals and trees. Within those adult organisms He placed the seed, potential and power to create the rest. Adam and Eve were introduced into the story grown. That was the end. Fully man. And God said, "It is good." And He left them to start at the beginning. So assuming the premise, it's not a stretch to see that God can create something in perfection and place within it all that it needs to fulfill it's purpose, which back then was simply to obey God, watch over the earth
and multiply. With that being the purpose i think God is able to handle His business.
Everything comes to this planet fully loaded, even you and I. As we move through life we get triggered by things that drive us in directions that we don't really understand and can't always verbalize. Nobody is here by chance every life is valuable because God made us. Bottom line, our purpose can only be found by seeking the heart of God.
