Rav Elchanan Wasserman asks a similar question in Kovetz Ma'amarim 1.
He writes that just by looking around the world in a simple manner, one is aware that G-d created the world and one does not need to be convinced by complicated philosophical arguments.
He brings evidence to this approach from the fact that the Rambam counts belief in God as one of the six hundred and thirteen commandments. Since every thirteen-year-old Jewish boy and twelve-year-old Jewish girl is obligated in this commandment, it is clear that belief in God does not require intense philosophical training or advanced intellectual ability. Additionally, the Halakha obligates every gentile to believe in God and fulfill the seven Noahide commandments, including even those whose lifestyle does not allow for academic achievement or intellectual advancement. This expectation would be unjust if belief in God is not easily attained by any normal human being.
R. Elchonon asks if it is a basic fact how can anyone honestly doubt the existence of God?
He answers that in fact it is impossible to honestly doubt God’s existence. Rather, R. Elchanan finds the explanation for the phenomenon of disbelief in the Torah’s prohibition of bribery. The Torah, when forbidding the acceptance of bribes, explains that “you shall not take bribes, for bribes blind the eyes of the discerning” (Devarim 16:19). Bribery has the power to corrupt the intellect and prevent one from thinking logically, as evidenced by the testimony of the Torah and the many stories of Talmudic sages whose judgment was biased by a whiff of bribery. If a small sum of money has the power to corrupt our reasoning, then certainly the bribe offered by the evil inclination – i.e. that if we deny God’s existence then we can then indulge our passions without restraint – has the power to blind us to the truth and pervert our intellect to the extent that we can deny the undeniable fact of God’s existence. The sole explanation for disbelief is that it stems from a moral failing. One who is beholden to his desires will experience a strong subconscious bias to reach a conclusion that justifies his lifestyle, and will therefore conclude, against all logic, that God does not exist.
@DoubleAA Look at the Chovos Halvovos 1:6 who brings a parable to explain the absurdity of atheists.
Once a rabbi met with a king. The king asked him the question, “How do you know of the existence of the Creator?” The Rabbi asked the king to leave the room. On the table was a quill, an inkwell and some paper. While the king was out of the room, the rabbi wrote a beautiful poem on the paper. When the king returned he noticed the poem and was amazed at its poetic style. The ink was still wet and the king praised the rabbi for writing such a beautiful poem. The Rabbi replied that he had not written the poem, rather, he had taken the inkwell, poured it onto the paper and the letters had formed themselves.
The king ridiculed such a suggestion saying that it was impossible for the ink to arrange itself into a single letter, let alone a word, let alone a sentence, and certainly not into a beautiful poem! The rabbi replied, “There is your answer. If the ink can't form a poem without the hand of a poet, then certainly the world, which is infinitely more complex than the poem, could not possibly form itself without the hand of a Master Creator!”
