The Sun god is also known as 'Savita', which means - one who creates, 'SAVITA SARVASYA PRASAVITA' (Nirukta -10/31). According to the Rigveda the Sun god situated at the centre of the solar system is an inspirer of all, pervader of the internal parts and an embodiment of almighty god.

When Brahma manifested himself by breaking the egg, then he pronounced 'OM'. This Omkar itself is the supreme soul and the very physique of Sun god. The four Vedas emerged from all the four mouths of lord Brahma, which were glowing by their own radiance. The powerful radiance emanating from the 'Omkar' covered the radiance of the Vedas and ultimately all of them unified. This very Vedic appearance of 'Omkar' is the sun god. This radiant sun was the first manifested during the times of creation, hence it was called 'Aditya'.
Once the demons, the titans and the monsters unitedly fought with the deities and snatched their power and authority after defeating them. 'Aditi'- the mother of the deities did worship of sun god to get protection from this calamity. Being pleased with her the sun god took incarnation as her son and established the eternal path of the Veda after defeating the enemies of the deities. He is called Aditya also for this reason.
