what should i even say?

Sure you can! But as you know my next question will be what is your basis and or criteria for your objective morality?

The objective reality that we share, and our nature in it as biological agents. There are a set of baseline facts that we can know for objective certainty; if my pain reaction is triggered, this is generally due to an objective physical harm being done to my person. Therefore, generally speaking, pain and harm are immoral, because they're unpleasant and harmful. Life is preferable to death because, well, we've got this one confirmable life, and more importantly those that think otherwise aren't around to inform us about whether their way is better.

And we can keep going along that line, defining those things that are beneficial or harmful for us, and using those general rules to construct an objective morality that is subject to change and improvement as we learn more.

Objective standards are really quite trivial to come across, in that sense.
