Yes, they would have scared the **** out of me, had I been alive back then!!! But I guess people got used to them, but probably steered clear of them at all times.
The nice thing is there is actually alot of info out there about these giants, We recently went to a local serpent mound in southern OH, it was built shortly after biblical times and according to the many informational videos and guides there, they think some of these giants were mound builders, they found overly large tools and a few skeletal remains, but not enough for a complete person, so it appears they did not stay here after the mounds were done. It is amazing to see, you should check it out if there is one near to you.
There is also quite a few private collections where some of these giant skeletal remains can be seen, the skulls are very interesting, they all have double rows of teeth and are missing one of the ‘plates’ that normal humans have, I saw an interview with a doctor that was examining one of these skulls, he went into great detail about the differences between that skull and a normal human skull, it is pretty amazing. Much of this can be found with a quick Google search, but trust me, you will have to sort thru the fakes and hoaxes too, there is alot of that out there, but look for reliable, credible people talking about this, that will lead you in the right direction (usually LOL)
I find this topic extremely interesting, but it all boils down to just another attempt of Satan to corrupt mankind, but knowing there was giants roaming around back then is still interesting, to me anyway, I realize many people do not find this very interesting and many try to say it is all fake, but this is to be expected, there is usually an underlying agenda if you look deep enough, plus, Satan does not want people to know these beings existed, his greatest trick was making man think he, himself does not exist, so it makes perfect sense to me for him to discourage people from seeking this info out, or making it ‘seem’ fake, he does not want people to admit or even know he tried to corrupt mankind in anyway shape or form.
I still find it confusing the bible says they existed before and AFTER the flood, I cannot figure out why God did not destroy them ALL with the flood?
