The Buddha thought that we have attachments to things because, fundamentally, we are impermanent and unstable beings, but we try in vain to cause permanence and stability in our lives.

Explanation:

Buddha believed that attachment is one of the main causes of human suffering. According to him, we tend to be attached not only to things, but also to people, which is equally harmful, because we are, fundamentally, impermanent and fickle, that is, everything in our life is subject to change. However, we spend our lives trying to change that, and in the search for permanence and constancy we get attached to things and this causes us suffering, because everything changes, spends, breaks and goes away. In this case, Buddha says, that if we were detached, we would be happier and more satisfied with our reality.

The Buddha thought that we have attachments to things because,

fundamentally, humans have cravings for things that has not been reached or don't have yet.

Explanation:

Buddha was a philosopher, spiritual teacher and religious leaders who lived in ancient India. He was the founder of the Buddhism religion. He talked about attachement, clinging, grasping which is as a result of cravings or desires for things that have not been reached yet which lead to suffering. Suffering is as a result of cravings or personal desires.
