In glass these days you have two choices. Glass which is harder to scratch but far easier to shatter. OR, glass which is harder to shatter, but easier to scratch.
Apple along with ALL the other premium cell phone manufacturers went to harder to shatter, but easier to scratch.
Apple can't defy the laws of glass physics. But if you think you can create glass which is harder to shatter AND scratch at the same time, you will become richer than your wildest dreams.
In the meantime, since you likely can't do that, invest a few dollars in a screen protector to protect the very expensive phone you own, is the best option available to you.
