Simultaneously with India, also Africa and Arabia have collided with Eurasia. So the Himalayas have formed at the same time with a great number of mountain ranges, from the Atlas and the Pyrenees at the Western extremity, passing through many other mountains, e.g. the Alps, the Carpathians, the Caucasus, the Hindu Kush, the Pamir etc., until the Himalayas at the Eastern extremity.
