manna isn't called What is it? for nothing i guess

One word says a lot "must." LIFE 'must' be all inclusive and not just about us stupid humans and it does have a purpose and that is to evolve. Now that the invasive humans have entered the picture further evolution may include an important extinction, us.

The real meaning of life by a simple observation is to be born to eat to reproduce then die. Any other meaning is by our own design.

Life/living is its' own purpose...think of a dandelion growing through asphalt, or tubeworms deep in the ocean, they exist because life expands into all (even grudgingly) provided openings.
Life, you can't kill it.

The purpose of biological life is simply to exist, to live, to continue.

Yup agree

We are here, imho, by biochemical accident, and the universe, which is not cognizant, or conscious, can not give a damn. But, while we are here, we might as well hold one another's hands as we spin wildly through the void.

As a species, we’ve evolved, we are the only species that have a large number of people who sit around and contemplate their navels.

Other than propagating the species, there is no collective meaning. You need to make your own....

We attach our own meaning or purpose to life....it’s in our own gift. However...we don’t live in a vacuum, so we must be cognisant of the fact that our decisions and actions impact on others.

Post pretty good. To my mind. Exploring is a good purpose, and training yourself to be better at appreciating, is the route to happiness. Good luck with your journey.

Just to share my thoughts about your comments. Not any thing that is intended for debating arguing. Just for you to think about and take it how ever you want.

#1. You say, "the question that life must have a purpose, I never found to be true."

#2. You say, "The universe doesn’t have a reason to exist nor a reason not to exist.

#3. You say, "Religion tried to answer this question by saying it is all in God’s hands but religion in my view just uses magical thinking that only goes so far in answering the big question. "

First, let me use a common source for the meaning of life and from that you can understand the purpose of life.

From Google search for the definition of life:

the condition that distinguishes animals and plants from inorganic matter, including the capacity for growth, reproduction, functional activity, and continual change preceding death.

The later part of this definition gives us the purpose of life: ...including the capacity for growth, reproduction, functional activity, and continual change preceding death.

Second, for #2 above I will just simply say: the reason that the universe does not exist is because of the fact that it does exist. So, because the universe does exist, that is the reason for it to not exist.

Lastly for #3. I ask this "big question", but first I say: Religion ... pure and faultless is this: to help widows and orphans in need and avoiding worldly corruption. James 1:27

What religion are you talking about and does that religion have anything to do with big questions about helping widows and orphans while avoiding worldly corruption?

Agreed.
As far as I'm concerned, my life's purpose is whatever I decide it is.
That purpose may vary depending upon my mood.

Our existence is only a small speck in time. It only matters while we're here. In the end after it's over, our lives do not have any purpose
