2) Buddhist do not believe in eternal Gods or Goddess. Especially there is no
creator God.

The primary difference is that Buddhism has no deity (god or gods) while Hinduism is polytheistic (many gods).
In addition:
violence & spreading of Hinduism & also eating beef or hurting anyone. In a sense doing bad karma is not part of Hindu belief.
Some of the shared beliefs of Buddhism and Hinduism are rebirth and Karma
There were several concepts that are not shared by Hinduism and Buddhism. One of the most prominent is atma. According to Hinduism, all beings have an unchangeable, eternal self or soul. The Buddha instead taught anatta, that there is no self at all, that the self is an illusion.
Tradition
Buddhism is a religion that has some roots in Hinduism, particularly in terms of shared cultural and philosophical elements. Buddha, the founder of Buddhism, was raised in a Hindu culture and drew upon some Hindu concepts in developing his teachings.
Hindus and Buddhists have different sets of sacred texts. However, Buddhism came from Hinduism and hence both of their religious concepts would have similarities. One Correction. Buddhism did not come from Hinduism. Buddhism has no belief in any long-lived gods, have no defined or required rituals, no priests and no caste system Many early Buddhists practiced a very early form of Hinduism (actually closer to Brahmanism) but gave that up when they converted.
They believe in just one god to avoid confusion.
Sacred texts are shared between Hinduism and Buddhism, with both religions revering texts such as the Vedas and Upanishads. However, each tradition also has its own distinct scriptures, such as the Bhagavad Gita for Hindus and the Tripitaka for Buddhists.
Both Hindus and Buddhists believe in:reincarnationNirvanaan immortal presence for each person
both Hinduism & Buddhism share a common thought. That is to attain Moksha (liberation) or Nirvana (Liberation) in life.
Both Buddhist and Hindus believe in reincarnation (Being born again as an animal) Aupmanyav adds: Humans also are a species of animals. Both believe that the reincarnation would be according to the karmas (actions).
Buddhism evolved by that buddha shared his knowledge around Asia and the followers decided to become Buddhism. Today in 2012 there are not many people that believe in Buddha.
Hinduism came first. Buddhism was started by Siddhartha Gautama, who took parts of Hinduism and incorporated them into his ideas, as he was born into a Hindu family. These shared beliefs include reincarnation and karma, nonviolence and compassion. Buddhists believe want is the root of suffering (as stated in the Four Noble Truths) and must be eliminated, and similar thoughts are voiced in the Hindu Upanishads and Bhagavadgita. Both groups meditate and concentrate on their actions in this world, and originated in India.
