You do not need to know everything, obviously you were not created, you have a mother and father, you know how Biology works.
Good, but you are assuming my existence is just a biological chain without asking why such a chain exists at all. I didn’t choose my parents, my family, my society, or my country. Such major aspects of my life being fixed without my choice cannot be explained as a blind accident. There must be a will behind this arrangement.
My parents didn’t choose their parents either, and this goes back generation after generation. So the question is not simply about Biology. Biology describes the process, but it doesn’t explain the origin, the purpose, or the selection of circumstances.
To me, the most reasonable explanation is that there is a higher, intelligent cause who sustains this entire chain and assigns each person’s place, time, and situation.
If you think this conclusion is not logical, then I would genuinely like to hear why, and how you explain this chain without appealing to intention or guidance.
That is the same for every living thing on the planet, life cycles are known in exquisite detail and none of those details involve a creation.
Life cycles are understood, yes, but that only explains how living things continue, not why they exist in the first place. The presence of ordered biological systems, genetics, and stable natural laws does not explain why these systems exist at all, why the laws of nature are so precise, or why there is life instead of nothing.
Science describes the mechanism, step by step. It cannot explain why the entire system came into existence, why it is law-governed, or why anything exists rather than nothing.
So saying that understanding life cycles removes the need for a creator mixes two different issues. Knowing the process does not answer the question of the origin or cause behind the whole system.
