Non-Aliyah immigration - Would it be possible for someone with absolutely no Jewish ancestry or ties to Eretz Israel, to obtain an Israeli citizenship?

Hello, dear friends from Israel!
I'm Polish, and I absolutely love Israel (Technically we have more Israeli flags at our home than Polish ones lol), but I don't have any Jewish ancestry, nor any other possible ties to Israel. I have thought plenty about ways of obtaining an Israeli citizenship, but from my research online, I would either have to be Jewish, or convert to Judaism, and well, I'm Christian.

So, my question is, if I, in the future, wanted to Israeli citizenship, would it be possible for me?
Also, on the topic, would I still be able to keep my Polish citizenship?

תודה רבה, חברים!
