Why did early humans migrated eastward to the fertile crescent rather than north to europe?

Explanation: The early humans migrated east to the Fertile Crescent instead of northern Europe because despite having similarities in the climate of Europe in general, it offered many mountain systems that triggered the creation of large tributaries, as they were the Nile River the Tigris and the Euphrates, therefore there was much more water and the rainy rainfall was more constant. These aspects favored the irrigation of forests, therefore wildlife conditions were optimal. Similarly, hunting and fishing activities were abundant due to the geographical conditions and resources provided by these important rivers located in the Fertile Crescent, which greatly favored the first humans preferring these territories to emigrate to northern Europe.
