What makes 飲んだ、and 飲んである different?

Don't they both describe the concept of drinking in the past?

More generally, what are the differences between the past tense of a verb, and
the auxiliary verb ある？

How are 飲んだ、and 飲んである different？
Where does 飲んである come from? I can't think of any legitimate construction off
the top of my head. 飲んでいた？

飲んだ is the simple past of 飲む. 飲んでいた is the past progressive or past perfect.

[Later edit] The context for 飲んである is like 冷蔵庫に入ってる牛乳が飲んであった？

Then this 飲んで is a 連用形 word modifying ある and the subject is 牛乳 (and naturally,
the subject of 飲む is someone who drank it)
