So you think that humanity is a result of mere chance?
Maybe you believe that every true statement could, if we knew enough, be expressed as a statement about physical objects: sub-atomic particles or force-fields or something like that. (Sometimes called "Materialism".)
Or maybe your scepticism about any creative purpose behind the world is more subtle than that.
All such views are implausible.
Some relevant material is discussed elsewhere in this site under the headings "Reason" and "Determinism".
