Use cash for short-term certainty
Money needed for emergencies or near-term spending generally needs to be accessible and protected from market falls. That is why an emergency fund is normally a cash-saving goal rather than an investment goal.
Investing is for accepting uncertainty in pursuit of growth
Investments can rise and fall and there is no guaranteed return. A longer time horizon gives you more time to ride through market movements, but it does not remove risk.
Consider expensive debt first
If you have costly borrowing, compare the guaranteed interest cost you are paying with the uncertain return you hope to earn from investing. Priority debts and essential arrears require separate attention.
You can use both
This is not always an either/or decision. A household can maintain accessible cash for emergencies while investing separate money for long-term goals.
