I think it would be good if when we started to draw our designs, each figure was housed from the beginning within a layer, to start each project in a more orderly way. And I think they could save us the trouble of creating layer 1 ourselves.
I think Illustrator does it like this, in the layers panel every new document has always "Layer 1" created by default and then all the shapes that are drawn are stored within that layer.
*Also in every "Artboard" created, I think its "Layer 1" should be created automatically.
