This is absolutely false and it is difficult to understate how false it is.
God’s love for us didn’t begin on the cross or even at the beginning of the universe. It goes from eternity to eternity. So, seeing any part of history or any aspect of the natural world as irrelevant or a question not worth exploring is a deficiency in our appreciation for God. The Incarnation and the Passion are of course pinnacle episodes of God’s humility and love, but He permeates everything and everywhere and every time.
There are several sources of beauty from which we draw an increased love for God and for creation (and when properly ordered, to love creation is to love God and to love God is to love creation, because you cannot fully isolate an artist from his workmanship) This includes the natural sciences, the social sciences, art, music, drama, literary works, and of course prayer and sacraments, which are the ultimate intimacy between a person and God.
Your philosophy is stemming from the fundamentalist Christian philosophy that to know less and to contemplate less is to be more holy and more pure, but this is not so. It is true that simplicity is a virtue, but it is simplicity of intention which is virtuous. That is: to approach God with the simplicity of a child that trusts wholeheartedly in their Father, even if they loss everything and everybody abandons them. It is not a simplicity in terms of a lack of any appreciation for exploration or discovery. The Church is rich in saints who were deeply inquisitive along with many of the Jewish heroes of the Old Testament. They were often criticized and persecuted by their contemporaries by asking questions that were deemed useless, but they persevered.
A scientist has a noble vocation and he or she gives glory to God.
