What does it mean when two people think alike?

I remember in the past when I "was" a christian in my room alone and chose to pick up the bible, I had read "in the beginning God created the heavens and the earth"
And it made me think to myself where is the other heaven/s and what types of heavens are they?
On that same day or the next day I remember my Dad asking my family and I the same question, that moment I felt like God was trying to tell me something or give me a warning because my dad had exactly the same thought after I had read it without even speaking to anyone about it.
