The bible claims there are streets paved with gold in heaven
Why?
Gold is a soft/malleable metal... you wouldn't be able to drive anything heavy on gold roads
Angels can fly right? Why do angels need roads at all? Can't angels teleport or whatever?
Perhaps sapphire, or diamond, or unobtanium... but why gold?
Is it because the people who wrote the bible thought gold streets would be tempting to a desert dwelling tribe?
Gold bars are made from the soft malleable metal that you are describing but hardened because it is moxed with copper. THis gold bars weighs a lot and are valued a lot and can withstand some of the greatest pressures just see the 5 star hotel in dubai.
People have legs right? Canmt they just walk or run or whatever? Why do we need bikes orcars at all when walking can be less stressing to the environment
