How exactly would a thicker atmosphere make a planet more habitable than Earth?
My friend said an atmosphere 3 times Earths current one on another world would increase the change for life especially in the oceans based on currents. I thought the transport of cold to warm water is dependent on temperature. A thicker atmosphere would decrease temperature differences. Water may only vary between 90 and 50 degrees with a thicker atmosphere instead of the 100 and 28 degrees it has now. So wouldn’t an increase in atmospheric pressure decrease chances for life?

Does your friend have any evidence, or even speculation from a reliable source? A thicker atmospheric pressure might inhibit certain chemical reactions that the precursors to life needed, reducing the chances of life evolving. Or it may do the opposite and allow life to evolve faster. Since we haven't found life anywhere else, we can't know.
Since Earth is the only planet so far known to harbor life, any conditions on other planets that deviate from those here would decrease the odds of life evolving there.

Try the biology, meteorology and oceanography forums.
People there know far more about these subjects than astronomers do. We specialize in stars, planets, meteors and galaxies here.

None really to tell the truth
For myself at least, I am happy enough the way ours is

I don't know that it would.
Ask your friend for the scientific references for his statement.

you can't lose with ad hoc statements!
science is off the table in the race to kill the ecosystem.
The public is way more receptive to ad hoc statements.
