Our wires are getting crossed here because of the differences in the use of the word 'void'. I'm saying the life we know is not devoid of other life, you are saying life is devoid of meaning. I think you accept that life exists, so the question moves onto what meaning does life carry...
There's an important point to consider here, and I hope you don't take offence... perhaps the reason you believe life is devoid of meaning is because you're asking the wrong question...
Let's consider the question... What is the meaning of a tree?
A person asking such a question has set out to find a succinct answer that fits with their understanding of what constitutes meaning. If they cannot find an answer, their conclusion is that trees are meaningless. However, this is us projecting our desires onto the tree, what we're really asking is 'what message do you have for me?', and message implies there was a sender of the message, so for those that do not believe in a higher power there is no sender of a message, so really you could predict the answer before its even asked (based on who is answering it).
Furthermore, it's important to understand just because a question is simple to ask, does not mean the answer has to be simple, or even mean there is an answer at all. Let's say I asked you... What do words mean? The question was posed in 4 words, and is a valid English sentence. However, when you think of answers, you see that the question is nonsensical, words don't have one meaning, each word has its own meaning. The same is true of the question... What does life mean? The English used to pose the question is valid, but the combination of words rules out any single answer.
Furthermore, there's a difference being meaningless and worthless. Going back to the tree example, if a tree was worthless the environment it existed in would not be changed depending on whether it existed. However, we can see that the tree has an influence on the world around it.
I've stopped the tree example there, because there's one more point that must be addressed otherwise this conversation is unlikely to progress. Whilst the 'meaning of life' question does not make sense, the reasons for asking it do, and that is to work out what we should do with our life. Whilst I still maintain that 'life is what you make it', I think it'll be helpful to share a little of my personal story and philosophy.
In 2012, I tried out a religious retreat, and whilst the people there were well intentioned, I reacted badly to it, which resulted in quite a bit of soul searching. Something that helped me balance myself what the teachings of Socrates, in particular that he was the wisest man because he knew one thing... that he knew nothing. This helped me change my perspective on life... instead of reaching up for answers about higher purpose (that I could never claim knowledge of), I instead chose to embrace the life I can experience now. I find value in enjoying life and in being a positive influence in the life of others. Seems like a perfectly fine approach to me, and you see I didn't need to find a universal answer to the 'meaning of life' question to choose this path either, your path is up to you.
As for universal ideal, perhaps the Golden Rule will suffice?
Thank you for reading this longish post.
