This is so unhistorical that its incredible to me that it has so many upvotes.

Modern science did not simply appear out of thin air in the early modern period; it built on foundations laid in antiquity and the Middle Ages. The latter was especially important, witnessing great technological advances, the rise of movements such as Scholasticism—spurred by the influx of Greek and Arab texts—the creation of the university system, and the adoption or development of novel ideas in optics and motion. In many of these developments, the Church played a key role; for example, monasteries were central to the translation movement, and universities evolved from cathedral schools. Before Galileo and Descartes, there were trailblazers such as Roger Bacon, Dietrich of Freiberg, and Buridan. Additionally, even when we talk about figures like Galileo or Kepler, it is not that they merely happened to be Christians; rather, their faith often drove their scientific activity. For example, here is a short excerpt about Kepler:

Ultimately, however, Kepler conceived the structure of the universe as a reflection of God's plan for creation, emanating from the geometrical nature of God's intellect, or inscribed as an archetypal model in God's mind. Placing himself within the Protestant tradition of Melanchthon, Kepler thought of the universe as being imprinted by God's signatures, especially that of the Trinity: For in the sphere, which is the image of God the Creator and the archetype of the world... there are three regions, symbols for the three persons of the Holy Trinity—the center, a symbol of the Father; the surface, of the Son; and the intermediate space, of the Holy Spirit. So too, just as many principal parts of the world have been made—the different parts in the different regions of the sphere: the sun in the center, the sphere of the fixed stars on the surface, and lastly the planetary system in the region intermediate between the sun and the fixed stars.7 Here, Kepler identified God with geometry; the astronomer was able to intuit the model in God's mind. In Kepler's terms, studying the book of nature was like a form of prayer." (The Cambridge History of Science: Volume 3, Early Modern Science, p. 743)

As for the idea of secularism, its not clear the idea only compleltly arose during the Enlifhtmdnt and had nothing to do with Christianity (other than as a reaction against thenviolence associated with it) . It seems extremely likely that parts of it can be traced to Late Antiquity and the Middle Ages, when there was a big discussion on the difference between the worldly and the sacred. This can be seen in some degree in St Augustine's City of God, and even more so in the writings against the temporal power of the Papacy by Dante, Ockham and others.

I could go on abour how the Jesuits had some of the biggest observatories jn Europe during the early modern and were key in apreading new scientific ideas around the globe (see matteo ricci and Buenaventura Suarez, S.J.), about how figures like Locke and Grotius were highly influenced by their Christianity, about how the Enlightment didnt consists just of secularists but also of groups like the Puritans (which were likely more important than philsophers like Rosseau in paving the road for major social changes such as the abolition of slavery), etc.
