I don't think they had steel 4000 years ago. I could be wrong. But, even if you did, you couldn't start a wick burning with just a spark. The spark needs to hit a very fine tinder and then quickly wrapped up with more tinder and then you blow on it until it bursts into flame. Then you transfer that flame to your already prepared fine kindling etc...
Sorry, I'm an old boy scout dad who loves to go camping.
Yes, you can if the wick is saturated with a proper fuel. I would like to refer you to the common cigarette lighter that has been around for a very long time. Same goes for the "permanent match".
I have struck two rocks together with resulting sparks. Perhaps flint and hematite.
Sorry, I am ALSO an old boy scout that goes camping AND is a bit of a pyromaniac.
