The bug thing is weirdly forgivable in that a lot of insects have forelimbs which are at least slightly-different looking and use them as manipulative appendages in addition to – or in rare cases, instead of – walking… see mantises, for an example of non-walking forelimbs. Most insects can also rear up and walk on four legs (and some beetles *have* to do so in order to run). And look at ants - most species carry things around with their forelimbs while only walking on their other legs! So given all that, it wouldn’t be too much out of line with reality to assume that insects have four legs… and two arms! I mean, most bugs do also walk on their “arms”, but so do apes. So, like, maybe God decided that this would be an easier concept for early humans to grasp and the whole arms thing was just, you know, implied.
That being said:
That Bible of yours says that Pi = exactly 3
This is definitely stupid because even during the days when the earliest books of the old testament were written, it was reasonably well-known in that region that pi was slightly larger than 3 and that 25/8 (3⅛) was considered “close enough”. (22/7 as a better estimate didn’t come until later.)
