>How long ago was this
ca. 7000 to 10000 years ago, so on a cosmic scale this is very recent.
>and how would we even know this is true?
all ancient cultures, all religions talk about this capture event and made similar observations.
there is also lots of geological and astronomical evidence.
like for example the vast electric scars on the earth like the grand canyon or the eye of the sahara or these basins at the north pole, the moon with its "lava tubes" which is also electrical damage, but also on mars like the Valles Marineris etc.
then there is also the matching planetary tilts, the (in the mainstream) unexplained planetary formation, the discovery that freefloating brown dwarfs are common in the universe etc.
basically there is a huge mountain of evidence.
