Does God exist, does Life have meaning and purpose? There is some evidence on both sides; the evidence is ambiguous...
Therefore, what is usually crucial is the assumptions we bring to the evidence - the assumptions shape the conclusion.
If we bring-to the evidence the inborn, spontaneous, natural assumptions (of early childhood) - the assumptions of animism (a living universe), the (theistic) reality of spirits, gods or God... then we become religious.
But if we bring-to the evidence the assumptions of modern, secular Leftist (hence anti-Christian) culture - then we become atheist, and indeed de facto nihilist in that we feel, suspect, believe and tend to act on the basis that reality is not really real.
Consequently, in order for modern secular people to become (really) religious, they must first recover their childhood assumptions.
