I have a hard time believing the concept of a bridge is so new.
A log across a stream is a bridge, of sorts.
Lasting bridges - anything bigger than a log across a stream, if you will.
Probably when we first started using stone, which would actually last long enough to make it into history.
The very nature of a bridge over a river also means the river is likely to change course and wipe out the bridge and foundations, so it's possible a number of crossings have been destroyed that are older.
bridges that survived in some form in the archeological record. there were almost certainly bridges - logs, rope bridges, etc., that predated these - but these survived in some preserved form - whether the wood was preserved or the cut stone foundations were preserved - there's evidence.
Why would they need a tossing after they had bridges 😳
BC counts down - 4001 BC is 4001 years BEFORE 1 AD. So 4001 BC is 1 year before 4000 BC.
Wait, so they had time travel back then? Why don't we have time travel anymore?
