If Egypt is 38,000 years old and Ziusudra's flood was 41,500 years ago, the ancient builders would have had approximately 3,000 years to reach Egypt after the flood.
41,500 minus 38,000 equals 3,500 years, not 3,000.
The arithmetic in the claim is incorrect. Subtracting 38,000 from 41,500 yields a gap of 3,500 years, not the 3,000 years stated by the speaker. This is a straightforward internal inconsistency in the proposed timeline, off by 500 years.
