[ELI5] Why current can kill you “easily” but voltage not?

I have encountered several articles and posts saying that what electrocute you and cause death is actually not the voltage but the current instead but is not clear to me how this works.

You are not a good electrical conductor. You’ve got a lot of resistance, so it takes a lot of voltage to run any current through you. Plus, you are mildly resistant to electricity, so a shock might startle you but it won’t harm you unless the source can provide enough voltage to run electricity through you **AND** at enough current to harm you. When you reach out to a doorknob and there is a spark, that’s a lot of static electric voltage, but not enough current to harm you. Touching that much voltage from a power plant, which can provide hundreds of amps of current, will electrocute you.
