Divine signs in creation (cosmic and terrestrial)

قُلِ ٱنظُرُوا۟ مَاذَا فِى ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۚ وَمَا تُغْنِى ٱلْـَٔايَـٰتُ وَٱلنُّذُرُ عَن قَوْمٍ لَّا يُؤْمِنُونَ

Say, "Observe what is in the heavens and the earth." But of no avail will be signs or warners to a people who do not believe.
