This is definitely not true from a philosophical level. Contemplation of an infinite god/cosmos, and the seemingly infinite nature of time are core aspects of early Greek philosophy, which heavily influenced the philosophy of each of the Abrahamic religions. As you started alluding to, the reason the west may seem more fearful of the infinite is likely because of widespread secularism, not western religion. An infinite cosmos is not nearly as scary to someone whose life purpose is appeasing an all good/infinite/timeless/immutable being, as it is for someone whose life purpose is managing their dopamine levels. Somewhat related: being someone who grew up in the west, I've always wondered how Hindus and Buddhists deal with evidence of the big bang. It fits fairly naturally into Abrahamic traditions that believe in a beginning to the universe. Though, it is fairly important to the philosophy of those eastern traditions that time and space (samsara) has no beginning or end.
