No, he is not right. In fact, over the years, some of the most committed Christians I have ever met were also outstanding scientists. To them, all creation was a witness to God's power and wisdom. Like the Psalmist, they realized that "The heavens declare the glory of God; the skies proclaim the work of his hands" (Psalm 19:1).
There is no conflict between science and faith -- not if we understand them properly. Science deals only with physical reality -- with things we can see and touch. But science is limited; it can't tell us about spiritual reality -- with things that can't be seen or touched. And yet God is real, and so is the human soul or spirit. In fact, God is more "real" than the things we see around us, because some day they all will vanish -- but God will still remain.
Don't apologize for your faith in Christ, and don't let the arguments of those who refuse to believe in God unsettle you. Instead, make it your goal to grow stronger in your faith, as you read God's Word and pray and have fellowship with other believers. Remember: In Christ "are hidden all the treasures of wisdom and knowledge" (Colossians 2:3).
Then seek God's will for your future -- not only for your career, but where you will go to college. And when you get there, seek out other Christians who can encourage you and help you stay strong in your faith.
