I'll try not to make it too deep or too boring, but since it's serious, don't make too much demands on me. XD.
The most widely written religion (believers and non-believers alike) is Christian-Catholic. Its members designed what we know as the "scientific method" used and polished over the years by all scientists in all fields of study (although many do not like it).
An example of a Catholic scientist is "Bishop Albert the Great 1193-1280 (or the Great) who, in addition to being a theologian and philosopher, was a geographer, astronomer, physicist and chemist. His works also include treatises on logic, metaphysics, mathematics, medicine and animal physiology. His method consisted in the observation, description and classification of the phenomena studied,** opening the door to future work, thus considering him to be a precursor of scientific progress."

⚫️ The irrational faith is based on esoteric beliefs without any theology, primitive and totally questionable beliefs, often passed down from generation to generation, more like legends or myths, things that are discordant in form or meaning such as magic and sorcery.
⚫️ Rational faith offers answers to philosophical questions with solid arguments from reason and even from the humble position of recognizing that it has no answers to everything, that there are things we do not know about God but that we are right about what we know, because science is something that is expanding and growing, they are not static concepts and theology as science is also subject to that norm.
We know less than 10% of what's in the cosmos but no one can deny that it exists.
I can't tell you what to believe in because everyone takes their own path and in this journey we are meeting each other and sharing experiences, the same reasons why I chose my faith may not convince you, but that's where the richness of finding God's way through the signs that he is guiding you more than by his own merit is.
