My life does indeed have meaning, purpose and value.
None of which comes from any belief in any gods.

Again, though, the issue is not
belief in God.
For example, suppose God exists, then a person’s life could have meaning, purpose, and value whether or not they believe in God.
Suppose God did not exist. Then a person’s life would not have any meaning, purpose, or value whether they believed God to exist or not.
A person might
believe that their life was meaningful without God, but that does not mean that it actually is.
For example, you have suggested that part of the reason you find life worth living is that you will 1. live on through your children and 2. have left a contribution to posterity. Now, this shows a
relative meaningfulness to life. Life is meaningful because of your effect on others. But why are their lives meaningful? Presumably for the same reason.
Now, someday human life and the universe will end, if this is true, then the last generation’s lives will not be meaningful because it will not have an impact on posterity or live on in their children. But, if not, then no lives were meaningful because the meaningfulness of any individual life was dependent on the lives after it.
For example. A is meaningful because it affects B. B because it affects C, C because it affects D… and Y’s life is meaningful because it affects Z. The the world ends. Z’s life did not live on into his children or positively affect posterity because there are no posterity. Therefore (by your two reasons), his life was not meaningful.
But it gets worse. Trace this backwards. Y was not valuable on his own, but only because of his positive effect on Z (which assumes that Z was meaningful. But if Z. was not meaningful, how could Y be? And if not Y, then not X… and so on, until even A was not meaningful.
Or put is slightly differently, without God and immortality (not
belief in them, but their actual existence), then the life of everyone comes to the same no matter how they lived. The scientist who worked to better human life and the dictator who worked to destroy it all come to the same. In either case, human life ends and, as one writer put it, remains only a story, and actually not even a story forever and ever.
Some people say that without God we must create our own meaning, but this is precisely the problem. Without God, we might ascribe a meaning to our actions, but this would only show a subjective meaning, not any objective meaning. That means that a person who finds killing innocent people meaningful is no different from a person who finds loving his family meaningful. Neither action is more objectively meaningful than another; rather, both actions are meaningful (or “true”) for the people who do them. In both cases they create their own meaning, and there is nothing to make one more objectively meaningful than another.
On the other hand, if God exists, then what we do does have eternal significance because there will be eternal life beyond the end of the word, and some actions (love of family and neighbor) really could be more objectively meaningful than others (drinking oneself into a stupor night after night). Some fuller explanations thereof
