hello i would like to know at what point does something come into existence, for an example take a painting does it come into existence the second the painter thinks of it and can see it in their minds eye(because can you think of something that doesn't exist)or is it when the painter first makes the first brush stroke on the canvas or is it only when the painting is completed and others can see it. It could also be said that the painting always existed because all the materials the painting is made out of was already here in one form or another, they were just never put together in that certain way before. What i really want to know is does something exist simply because someone can think of it and see it in there mind or does it have to be seen touched or smelled in the physical world.For another example, the computer you are reading this on definitely exists because you can see it and touch it and so can others but the programs on it like Microsoft word or excel do not physically exist, you can not touch them or weigh them or smell them but we know they exist, so back to my question at what point does something go from nothingness/non-being to existing in the universe.
