Who owns all the ETH?

Excuse me, could you possibly clarify who actually owns all the Ethereum, or ETH, for short? I'm quite curious about this matter as it seems to be a crucial aspect of the cryptocurrency world. With the vast sums of money and power associated with ETH, I'm interested in knowing who holds the reins. Could it be a single individual, a group, or perhaps an anonymous entity? Could you provide some insight into this matter? Thank you for your time.
