Feeling alone in this world? Thinking that there has to be more to it?

You are right! That feeling and those thoughts are from your conscience speaking to you!
You see, when a developer codes a program, they insert their signature into it. Likewise, an auto company will brand their vehicle with their brand.
In the same way, the Creator has instilled a consciousness into humanity to know right from wrong.

“For when Gentiles (you) who do not have the Law do instinctively the things of the Law, these, not having the Law, are a law to themselves, in that they show the work of the Law written in their hearts, their conscience bearing witness and their thoughts alternately accusing or else defending them, on the day when, according to my gospel, God will judge the secrets of men through Christ Jesus.”
‭‭Romans‬ ‭2:14-16‬ ‭NASB‬‬

If as some say we are just evolved cell membranes, we would not have a consciousness and would be just a dog eat dog world.

As most are aware, artificial intelligence has been making great leaps and bounds.
Think about it! The work required to first think about making a robot, the design, making parts, the fit and INSTALLING the software perfectly mirrors the human!
The robot nowadays can be fully autonomous and even turn on their creators (humans) as some scientists have warned! We have done so as well.

Do you see anyone claiming robots are just a freak accident that happened from an explosion? No because that is silly. Yet the lie is still perpetuating that with MILLIONS of years it all happened by itself.
How preposterous is this?
So now that you know there had to be a Creator out there, WHO is this Creator?
Why it’s the One whose Son Jesus came down and died for us as history attests.
To further find out, start with the New Testament of the Bible, the book of Matthew and read on!
Also, ask for understanding and revelation and it will be answered!
God bless you in your endeavor!
If you feel curiosity at this, that is the Holy Spirit giving you a nudge!
