WTF? Way to go off on a tangent.
Avoirdupois weights are far more complex than you imagine btw. You can blame the French for them too.

And as for the concept of Zero, sorry but what the fuck does that have to do with your faulty logic? Your shit still makes no sense.
Also, zero is not exactly an amazing discovery, it's not like every culture in the world had zero. Oh wait, they did. You don't get the importance of zero in the decimal system, it's not the role of zero as a number, but of the numeral zero's use as a positional digit that enables the decimal system. Although the use of zero in not actually essential, the use of any positional digit works the same.
Anyway, your logic is still faulty.
<Seseme logic>
Oh lets see, zero was first written in South America by the Olmecs, therefore the Indians must have copied them, all zero's everywhere originate from the Olmecs.
