Let me ask a related question. Do you believe that a giant meteor struck the earth at the site of the
Chicxulub crater? This is believed to be behind the mass extinction event that wiped out dinosaurs. Where are the "ripples" left behind from that?
There are SO MANY existing ripples from the Chixculub impact. Here's a small sample:
The remains of the physical impact crater itself, as well as the related geological structures in the surrounding area like crustal weakenings and sinkholes.
The presence of impact deposits and melted rocks down to at least a depth of 10 km, along with the presence of materials from the ejecta blanket spread over an area of thousands of kilometers.
The type of sedimentary rocks laid down in the area after the impact.
The presence of magnetic and gravatic anomalies at the crater site.
The global presence of elevated levels of iridium in sedimentary rock strata aged (roughly) 66 million years old.
The presence of sedimentary rock layers laid down from the tsunamis following the impact (with geological evidence up of their formation up to 6000 km away from the impact site).
Fossil evidence of a simultaneous mass extinction in the area around the impact site (out to a distance of about 2500 km), and then a delayed mass extinction out to about 8000 km from the site.
Although the timing is not consistent with the apparent timing outlined in the Bible, I think this meteor strike is the same event as the Biblical Noah's flood.
Why?
What possible reason could you have to think that an impact 66 million years ago, before humans were even a biological reality, is the same as a flood story that is disticntly similar to those of neighboring near-eastern cultures in the same time period?
We know these things:
Humans experience floods. Particularly cultures that developed alongside major river systems (like the Tigris, Nile, Euphrates and Jordan rivers).
Humans ascribe agency/anthropomorphise natural events.
Humans are hardwired to tell stories. Humans also borrow stories from nearby cultures.
Humans use supernatural beings as a fill in for gaps in knowledge.
Given that knowledge, why would you think that an impact that pre-dates human-like creatures by about 64 million years is the basis for the Biblical deluge story?
