As per the out-of-Africa theory, the earliest homo sapiens to leave

Question

As per the out-of-Africa theory, the earliest homo sapiens to leave Africa crossed the Red Sea and spread along the coast of Asia, making their first major settlement in the Deccan (India, Asia) roughly 45,000 years ago. However, the discovery of 46,000 to 49,000 years old homo sapiens settlement in the Bacho Kiro caves (Bulgaria, Europe) suggests that the earliest homo sapiens to leave Africa actually spread towards Europe, migrating along either the Danube river or the Mediterranean coast.

Which of the following, if it were discovered, would be relevant evidence against the conjecture above?

A. The oldest positively identified homo sapiens fossil is dated to be 58,000 years old.
B. 6,000 years ago, the depth of the Red Sea, between Africa and Asia, was considerably lower, due to glaciation.
C. The climate at the Bacho Kiro site is more temperate than that at the oldest known Deccan site.
D. The site in Bulgaria where the fossils dated to be 46,000 to 49,000 years old has been continuously occupied since the time.
E. Some Asian sites of homo sapiens migration predate any sites found in Europe.

Option E  correctly portrays in this problem that the migration of Homo Sapiens across some asian sites predate any sites found in Europe, this gives us reason to believe that the discovery of homo sapiens 46,000 to 49,000 years ago could have actually gone to Asia after all and not Europe.

X settled 45000 years ago in India.
But discovery of X settlement in Europe which dates 46000 to 49000 suggests that X first settled in Europe.

We need to find an answer that tells X settled in India first and not Europe.

Option E  brings in new evidence that some sites found in Asia predates any site found in Europe. This supports the view that X settled in India first and not Europe.

earliest homo sapiens left africa and settled in deccan 45000 years ago. 
 but found 46000-49000 years old homo sapiens in bacho kiro caves. 
 this suggest earliest homo sapiens to leave africa spread towards europe.

A. The oldest positively identified homo sapiens fossil is dated to be 58,000 years old. 
 thats good to know but doesnt tell me where they first settled. so out. 
 B. 6,000 years ago, the depth of the Red Sea, between Africa and Asia, was considerably lower, due to glaciation. 
 this is irrelevant to the argument. out. 
 C. The climate at the Bacho Kiro site is more temperate than that at the oldest known Deccan site. 
 nobody cares about this. reject. 
 D. The site in Bulgaria where the fossils dated to be 46,000 to 49,000 years old has been continuously occupied since the time. 
 that means more and more have occupied the site from there on. but this doesnt solve the paradox here. out. 
 E. Some Asian sites of homo sapiens migration predate any sites found in Europe. 
 that means asian sites were discovered first and then other european one. so this clearly destroy the paradox

The Breakdown
• The Original Theory: Homo sapiens left Africa, crossed the Red Sea, and settled in the Deccan (India) ~45,000 years ago.
• The New Evidence: Fossils found in Bacho Kiro (Bulgaria) date back 46,000 to 49,000 years.
• The Conjecture (Conclusion): Therefore, the earliest Homo sapiens to leave Africa actually spread toward Europe first, not Asia.
To weaken this, we need evidence suggesting that the migration to Asia actually happened even earlier than the Bulgarian site, or that the Bulgarian site doesn't prove Europe was the "first" stop.
Evaluating the Options:
A. The oldest positively identified Homo sapiens fossil is dated to be 58,000 years old.
This is irrelevant unless we know where that fossil was found. If it was found inside Africa, it doesn't tell us anything about the migration route.
B. 6,000 years ago, the depth of the Red Sea... was considerably lower.
The timing is wrong. The migration in question happened over 45,000 years ago. Conditions from 6,000 years ago don't impact the argument.
C. The climate at the Bacho Kiro site is more temperate than at the oldest known Deccan site.
Climate differences might explain why people stayed in one place, but they don't provide evidence regarding the timing or sequence of the migration.
D. The site in Bulgaria... has been continuously occupied since the time.
Continuous occupation doesn't change the age of the original fossils found there. It doesn't help determine if Asia was settled earlier.
E. Some Asian sites of Homo sapiens migration predate any sites found in Europe.
This is the correct answer. If there are sites in Asia that are older than the 46,000–49,000 year old site in Bulgaria (for example, a site in Asia dating back 55,000 years), then the conjecture that humans spread toward Europe first is proven false. It directly attacks the timeline the author is using to favour Europe.
