​If I have hey I create create art, do I own the copyright to that art?

Edit: the answer seems to be no. If anyone else would like to comment on this, I have a second question. Would it be advisable for me to put AI art on my website temporarily? And then once I have cash flow I can hire an artist to make me an original piece of art?

Does anyone see an issue with this?

I kind of want a cartoon mascot for my business. It would be a fairly simple design. Are there any AI sources I can use to create this art and then I would own the art?
