This question is about religious beliefs and faithfulness, and the answer will depend on personal faith and belief. In the traditional perspective of Hinduism, Brahma, Vishnu and Shiva are recognized as the main deities.
Brahma, Vishnu and Shiva are known as Trimurti, which means that these are different forms of the same God that perform the work of creating, operating and self-destructing the world. Apart from these, there are many religious and philosophical traditions and ideologies regarding the existence and appearance of God above Brahma, Vishnu and Shiva.
In some religious sects, Ananta and Advaita Brahman are recognized as the highest God. This supreme God is also called Brahmananda, Parabrahma, Niranjan, and Alakh. This is followed in Vedanta philosophy.
Past and present, according to many religious sects and traditions, the God above one, Purushottam, Akhand Brahman, Beyond Nature, is also known as Alpha and Omega, vishvadhishtha, etc. Each of these definitions and names is a representation of the existence, appearance and subsistence of God.
The good thing is that in our world there are so many religions, philosophical traditions and differences that provide us with the need to think about the admissibility of different types of divine truths. It will depend on the personal belief and study that every person achieves over their faith and time.
