What evidence suggests the carbon-carbon bonds in benzene are different from bonds in alkanes and alkenes?

Currently, I have 2 thoughts on this. I'm not quite sure which one is right (or both wrong)

the ratio of carbon to hydrogen is 1:3 or 1:4, inbetween alkanes and alkenes

the ratio of the bonding of carbon to hydrogen is 1:1

The C-C bond distance in benzene is shorter than a C-C bond length in alkanes but longer than the C-C bond length in alkenes suggesting that the C-C bond in benzene is between a single bond and a double bond. Also, all of the bonds in benzene inside the ring are equal suggesting that we don't have some of the bonds as C-C and the others as C=C.
