The historical Buddha, Siddhartha Gautama, is not normally understood in Buddhism as a creator God. He is revered as a fully awakened teacher who discovered and taught a path to liberation. Buddhist traditions can describe Buddhas in highly exalted, cosmic, or devotional ways, but this differs from belief in an all-creating deity.

The historical Buddha
Buddhist tradition remembers Gautama Buddha as a human being who awakened to the nature of suffering, its causes, its cessation, and the path leading to cessation. His title “Buddha” means an awakened one.
He is therefore more than an ordinary philosopher in Buddhist religious life, but not a prophet of a creator God.
Why Buddhists bow to Buddha images
Bowing, offering flowers, lighting lamps, and chanting before Buddha images can look like worship of a god to outside observers. Buddhists may understand these acts as reverence, gratitude, recollection, merit-making, or devotional connection with awakened qualities.
Different schools explain the presence and activity of Buddhas in different ways.
Cosmic Buddhas and Mahāyāna
Mahāyāna and Vajrayāna traditions speak of Buddhas such as Amitābha, Vairocana, and Akṣobhya. Their roles go beyond a simple biography of Gautama, and devotees may pray for help or rebirth in a Buddha-field.
Even here, Buddhist cosmology does not usually identify a Buddha as the single creator of the universe.
Buddhism and gods
Traditional Buddhist cosmologies include devas and other heavenly beings. They are powerful but impermanent and remain within saṃsāra unless they attain liberation.
This is another reason the categories Buddha and god should not be treated as synonyms.
Best answer
Buddhists revere the Buddha as fully awakened, not as the creator God. Devotional language can be rich, but it belongs to a different religious framework from classical monotheism.
