The Notes are not what Daisy thought they were

THIS THEORY HAS SOME MAJOR SPOILERS FOR THE BASEMENT.

We have not been able to find any hint of Dad's notes. We've looked everywhere! They're not here. Or are they?

The notes are in the basement since that is the area that was locked off to us and that seems to be where Dad's lab was. As Daisy is forced into the basement by Alan, she discovers some odd things around. There seems to be dog bowls all over the place, jars with what seems like blood inside them, and locks of hair, which do not seem to alarm him too much. We are, however, discovering that there are other creations that have been living in the basement the entire time. Since Lithop, one of the creations that greets Daisy says that Alan is the "little one," we can assume that Alan was the last experiment done by her father before he left.

So now, Daisy is aware that Alan is NOT the only experiment, and is in fact, the latest one that he had done. Now that we know that he had tried many times to create life somehow, there must be notes somewhere in the basement. That seems to be where he worked on them, and we have not gotten to explore all of it yet. Daisy thought the notes would talk about how to care for Alan the monster, but the notes are actually about the failures and other monstrosities before Alan.

It is almost certain that Daisy will find the notes, since they were such an important trope to the story for many videos.

What might the notes hold? Is there any useful information about how to stop Alan? Had her father created something exactly like Alan before and he had to stop another monster? The notes may read like a diary or journal as her father explains the mistakes he made in his creations and his small victories. He clearly has not accomplished what he has set out to do, which will be included in the notes/journal. What was his intention? That leads to ANOTHER theory, he is trying to recreate his wife from her DNA.
